My dd 7 1/2 mos old 21# is currently in a RA RF. She has about 4 1/2 inches from the top, and in the middle slot-however I have a friend that wants to buy my seat (I just bought it about 5 mos ago, and only paid $160.) So I was thinking since I know she is about to outgrow it soon, I should go ahead get rid of it while I can and buy something else. SO the big question.... should I get the MA? or should I hang on to it as long as possible and see what she is when she really outgrows it to see if she is then forward facing and possibly go with something else? What would you do? Also- I need a smaller car seat for dh truck, right now the RA(we have 2) fits perfectly in the middle RF- MA is way way too big so what is something smaller that will accomodate her growing? Thanks in advance you guys are the best!!
