DS was the same - I stopped putting him at the table with us because not giving him food seemed so mean - we did start three days ago with BLS - he is 6 months today. My main reason for not starting earlier was how he sat up, his sitting up is still not great but ok (DD was sitting great by time started BLS at 6 months) and the fact even with BLS it is still more work than breastfeeding (A big reason to wait in my opinion :-) ) . He is very very keen on getting the food into his mouth now have started but isn't really swallowing yet - so for us was probably right to wait. Although looking back I think when I felt mean a few weeks back I could have just given him a piece of broccoli etc to suck on and he isn't really ingesting any so doubt would have done any harm. I think the other thing to remember is they don't know what food is, they don't know that food will take away hunger etc - they just want to do what they see others doing - so will probably be just as happy with something that looks food like to chew on.
