Ok moms, so my son is 5 months but weights 29lbs, he is also just under 30 inchs long and he does NOT fit in his infant car seat anymore . LOL I've been trying to so research on which car seat to buy based on his age, weight and height and everything I read I cant seem to get a good answer .. please no nasty comments, I do know he has to be rear faced, and in the back seat I'm not a complete idiot , I just cant use this infant seat anymore cause his feet are hanging out at the bottle but i also dont want to waste my money on a 4 in 1 carseat , but when looking at 3in1 carseats there are sooo many different kinds and systems and some seem to be for old kids , let me know what you all think please 😊
