Hello Sam. I went through something very similar with my daughter when she was younger and she didn't get rid of her bottle until she was four and a half!! Probably like you, I used to go to bed so worried that she'd not eaten anything, I ended up giving her bottles just so that I knew she had something in her tummy. It was a catch 22 situation. You say your son won't eat anything. Do you actually mean he won't eat ANYTHING, or is he very selective about what he puts in his mouth? I used to describe my daughter as not eating anything but she would, in fact, eat milky foods such as rice pudding etc. occasionally. My health visitor told me not to worry too much (once daughter had been assessed to make sure nothing was wrong) and I was told she'd probably 'grow out of it' once she started to eat meals with other children at pre-school/infant school. I can honestly say I was a very worried parent for a few years (ashamed to admit but, through desperation, I actually squeezed my daughter's cheeks together once to force her mouth open so that I could get some food in). However, my health visitor was right, she did grow out of it - now eats absolutely anything and everything and we both have a good laugh together about the trouble she put me through. Good luck :o)
