V.T.
As someone with a daughter with food allergies, I don't feed someone else's kid anything without talking to the mom first, since I don't want anyone feeding my daughter. However, I gave my daughter baby food with a tomato base at 8 months and she did just fine. I've never heard no tomatoes the first year, but other posters are right, they are very acidic and I've known kids to have reactions to tomatoes (rash on face).
