Jemima was never a floppy baby, and had headcontrol from early on, but I think there is a difference between holding head up and having confident headcontrol, I think baby should be thinking about food rather than staying upright in chair?

I have the book that my Mum had when I was a baby and it is so interesting as it says that 5kg is the time you should start baby on solids..... that would have been when Jemima was less than 3 months and I'm pretty sure some babies are born 5kg??

Times change, babies dont really, but the things around them do, different cultures treat babies differently and they all survive.

Get some help from a doctor or nurse that can see your baby in real life as there is no "wrong" there is just what is RIGHT for YOUR baby.
