so confused!!

So confused about when my baby should drop a feed. He has just turned 7 months and at the moment he has 4 8oz bottles a day plus I give him toast for lunch (doesn't always eat it) and then half a jar of baby food and a yoghurt for his main meal. However most people comment on how 'big' my baby is and I'm worried I'm giving him too much. Can anyone help me out? What does/did your baby eat at this age?
