Am i doing the right things as a mother?

My daughter is 7 months old and I have been giving her fromage frais, bits of mild cheddar cheese, mushed up egg with er and basic table foods on top of her regular feeds...she has had no reactions to any of these things but she does have a cold at the moment (so do I). My MIL keeps having a go at me for offering table foods at this age and now I just feel like I'm being a c**p mum. She also says thaty she shouldn't be using a sippy cup at the moment (she likes it better than regular bottles) and that my daughter shouldn't be having naps during the day (my daughter has had naps from day 1 and has slept through the night since she was 18 days old)....basically my MIL doesn't like the fact that I'm not raising my child how she wants me to....she also HATES the fact that I feed :(. Sorry for the rant lol basically my question is this - can I give my 7 month old the above items? Should she be using a sippy cup? And is everyones MIL the same as mine....
