Thanks, the seat he is in at the mo has about 1-2inches before his head will be level with the top and know its once they are eye level with the top that its then unsafe for them to be in there. I think Aaron is about average in hight and weight, but would have to check as have not had him weighed properly since 4mth. Our friends have the same seat we have just bought and I think it may be higher than ours...so today when we see then I have asked if we can put Aaron in it and see if it is higher(dont ant to take ours out of the box incase we do end up taking it back). I will check out that website to, thanks Trish.
Do you think we should move Aaron over to the side in a few month or so so he can get used to it?

Thanks
