Bassinet or Crib for the First Six Months?
One is outgrown in four months and solves the problem you actually have. The other lasts three years and does not fit next to your bed.

In this guide
The AAP recommends that babies sleep in the parents' room, on a separate surface, ideally for the first six months. A full-size crib does not fit next to most beds. That single fact is why the bassinet market exists, and it is the honest starting point for this decision.
Both products are safe when they meet their standard and are used as intended. The choice is about geometry, room-sharing logistics and money, not about safety, and it becomes much clearer once you separate those three.
What each one is
A bassinet is a small, portable sleep surface for a newborn, typically 30 to 33 inches long, low enough to sit beside an adult bed, and rated to a weight limit around 15 to 20 pounds or until the baby can push up on hands and knees. That last condition usually arrives first.
A crib is a full-size fixed sleep space, roughly 52 by 28 inches, rated from birth to somewhere around 35 inches tall or when the child can climb out. Most convert to a toddler bed afterwards.
They are governed by different federal standards. Full-size cribs are covered by 16 CFR Part 1219, which incorporates ASTM F1169. Non-full-size cribs and play yards fall under 16 CFR Part 1220 and ASTM F406. Bassinets and cradles have their own standard. Every one of them is mandatory, so a compliant product in any category has passed a real set of structural tests.
The case for a bassinet
It fits where the guidance wants the baby to sleep. This is the whole argument. Room sharing for six months is a specific recommendation with evidence behind it, and it is much easier to follow when the sleep surface fits in the room where you sleep.
Night feeds are less brutal. A bedside bassinet with a drop-down or mesh side means a baby can be lifted without a full stand-up-and-walk. Over three months of two-hourly wakings, the difference is real.
Portability. A bassinet on wheels moves between rooms, which means daytime naps happen where you are rather than upstairs behind a monitor.
It is cheap relative to its job. A good bassinet is a fraction of a crib and it is doing the harder part of the first year.
The case against a bassinet
It is outgrown fast, and usually sooner than the label implies. The limiting condition is very often "when the baby can push up on hands and knees" rather than a weight figure, and that milestone arrives for many babies around four to five months. Buying for six months of use and getting four is common.
It is a second purchase. You will still need a crib.
Quality varies more than in cribs. The category includes premium bedside sleepers and very cheap fabric-and-frame products, and the difference in stability and mattress quality between the two ends is large.
The case for going straight to a crib
One purchase, three years. No second product, no transition, and the money goes into the thing you keep.
A better surface. Crib mattresses are held to a federal standard that includes a firmness test, added specifically to address suffocation risk from overly soft surfaces. It is covered in what firm means on a crib mattress. Bassinet pads are thinner and the category is more variable.
No transition. Moving a baby from a bassinet to a crib at four months is a real disruption in some households and a non-event in others, and you cannot tell which yours will be in advance.
The case against going straight to a crib
It usually will not fit in your bedroom. A crib needs about four and a half feet by two and a half, plus clearance, and in most bedrooms that means the crib is in the nursery and you are not room-sharing at all.
Night feeds mean walking to another room. Every time, for months.
A crib in the bedroom is a compromise anyway. If it fits at all, it typically fits somewhere awkward with the side rail facing the wrong way.
The answer most families arrive at
Bassinet in your room for the first four to six months, then move to a crib in the nursery. Most families end up here and it is not a failure to plan, it is the arrangement that matches the guidance to the actual size of rooms.
Two ways to make it cheaper. A play yard with a bassinet insert meets 16 CFR 1220 and does the bassinet job, then becomes a travel cot for three years. It is less elegant beside a bed and considerably better value. A bedside sleeper that attaches to the bed frame gives the easiest night feeds of anything in the category, at a premium price, and it is the one product here whose value is concentrated entirely in the first three months.
Second-hand is a reasonable route for a bassinet in a way it is not for a car seat, provided you can establish the model, check it against the CPSC recall database, and confirm the mattress pad is the original one supplied with it.
The rules that apply to both
The surface is what carries the evidence, and it does not change between products.
Flat and firm, with no incline. Inclined sleepers are banned outright, which is covered in what the Safe Sleep for Babies Act banned. The mattress must be the one made for that product, sitting flat with no gap at the edges. Nothing else in the space: no bumpers, no positioners, no pillows, no loose blankets, no soft toys. Baby on their back, every sleep, by every caregiver.
If a product's marketing describes a sleep surface as cosy, contoured or nest-like, read the standard it is certified to rather than the adjective.
Where this sits
Our cribs and bassinets roundup covers the specific picks in both categories and who each one is wrong for. If your reason for shopping is anxiety about breathing rather than about furniture, the evidence on that is not what the packaging implies and it is set out in do breathing monitors reduce SIDS risk. And if a pram carrycot is going to double as a daytime sleep surface, the same rules apply to it, which is worth reading alongside the stroller guide.
Questions people actually ask
How long do babies actually use a bassinet?
Often four to five months rather than six. The limiting factor is usually the developmental one, meaning the point at which the baby can push up on hands and knees, and that typically arrives before the stated weight limit. Plan for the shorter figure.
Is a play yard as good as a bassinet?
For sleep, yes, provided it meets 16 CFR 1220 and you use its own mattress pad. It is bulkier next to a bed and much better value overall, because it carries on being a travel cot for years after the bassinet function is done.
Can a baby sleep in a crib from day one?
Yes, and safely. The only real objection is that the crib usually cannot be in your bedroom, which makes room sharing for the first six months impractical, and room sharing is the part the guidance is specific about.
Are bedside sleepers that attach to the bed safe?
The compliant ones, used as instructed, are a separate sleep surface rather than bed sharing, which is what the guidance asks for. The conditions matter: correct attachment to the bed frame, no gap between the sleeper and the mattress, and the bed at the height the manual specifies.
What about a Moses basket?
It is a short-term surface, typically outgrown by three months, and it is only as good as the stand and the mattress. Check what standard it is certified to, and be wary of the decorative end of the category where the drapes and canopies are the selling point.
