dd is in a rear facing car seat still, she is 19lb 9ozs but is quite tall, her head is coming over the car seat alot now and i know thats not good, my problem is that mothercare don't recommend a forward facing seat till they are 20lbs+. Has anyone else had this kind of problem, i'm desperately trying to fatten her up she is 14mths as well. Should I get medical advice (and I know that sounds daft) but I think she really should be in a ff seat now
