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 chose to put on 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 3 important factors when choosing a carseat that is likely to fit a smaller baby well. First is the minimum weight rating. Many carseats are rated from 5 lbs. up. But many babies are discharged from the hospital weighing less than 5 lbs. and the hospital staff might not let you leave with your under-5-pounds-baby in a carseat that has a 5 lbs. minimum weight rating. Ideally, you want a carseat with a minimum weight rating of 4 lbs.

You’re also going to need lower-than-average bottom harness slots (ideally 6″ or lower), OR a carseat that comes with an insert cushion that goes under baby’s bottom which raises them up so that their shoulder level is even with, or slightly above, 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 (and don’t use any aftermarket strap covers if your carseat didn’t). In my blog 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.

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 baby store. 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 carseat.  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 support cushions. However, there are some safe, recommended alternatives to such products so if you’re looking for suggestions or advice (on this or any other carseat-related topic), please visit our Car-Seat.org forum and we’ll be happy to help educate you.

UPPAbaby Mesa preemie dollSince you probably don’t have a good lifelike 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 and smaller babies. All of the seats on this recommended list have been tested by either Darren, Heather or myself 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).
