Best Carseats for Fitting Preemies & Low Birthweight Newborns

Everyone understands that low birthweight babies often come with challenges. However, most expecting parents don’t consider the possibility that the carseat they bought, or received from their baby registry, might not fit baby well if she or he arrives early or is smaller than average at birth.

Of course, you often have no idea ahead of time that you’re going to have a preemie or smaller-than-average term baby. But if you’re expecting multiples, have a history of preterm labor or just a history of delivering small babies then you really want to be prepared with a carseat that is likely to fit the baby/babies well – regardless of whether they’re 4 lbs. or 9 lbs. at discharge.

There are a few important factors when choosing a carseat that is likely to fit a smaller baby well.

• Minimum weight rating. Some seats are rated from 5 lbs. up. Ideally, you want a carseat with a minimum weight rating of 4 lbs.

• You’re also going to need either lower-than-average bottom harness slots (ideally 6″ or lower), OR a seat that comes with a lower body insert cushion that goes under baby’s bottom, boosting them up a little bit so that their shoulder level is even with the bottom harness slots.

To clarify, in a rear-facing carseat, you want the harness straps to be situated “at” or slightly below the child’s shoulder level.

In order to evaluate this properly, you may want to remove the harness strap covers if your seat came with them. In my review photos, I almost always ditch the harness strap covers because, in my opinion, they just tend to get in the way more than anything else when you have a small baby.

Speaking of getting in the way, I want to take this opportunity to educate you on the plethora of aftermarket carseat stuff that lines the shelves of every store with a baby department. With the exception of a blanket to put over baby in cooler weather, you only want to use the things that came in the box with your seat, or items made by your carseat manufacturer that are specifically approved for use with your carseat.

Aftermarket products may look helpful or useful but they can be a real detriment to proper usage so they are not recommended. Products like the Bundle Me are great for the stroller but should never be used with your carseat. Ditto for aftermarket harness strap covers and aftermarket infant head support cushions.

Since you probably don’t have a preemie doll at home to test your carseat with – you can rely on us to steer you in the right direction when it comes to carseats for smaller babies.

All of the seats on this recommended list have been tested by us using the preemie doll made by Huggable Images and we’re confident that these seats will provide a snug and proper harness fit for the vast majority of babies who measure at least 4 lbs. and 17″ (the size and weight of this particular doll).
