How old was your baby when you fed them baby food for the first time?

I gave my son solids at 5 months.  He started on rice cereal, them moved to bananas, mangos, peas, and the like.  I followed the guidelines in the Super Baby Food book - which are very different from other books I've seen.  (My son, for instance, didn't get most berries until after he was a year old.  Lost of kids in his playgroup were having them at 9 and 10 months.)

That said, I have a friend who didn't start her kids on solids until they were 9 and 10 months old.  They just weren't interested before that.  Know what?  THEY'RE FINE, and super smart.

Go with your gut, not with what we did.  If your child is 4 months and doing great on a bottle, stick with the bottle.  If he/she is 4 months and clearly hungry, try out solids.  There's a million methods and a millions experts who will tell you a million "this is the way it must be done" rules.  Best way to navigate: go with your gut.

I started my daughter on a little cereal in her bottle when she was about three months old because she was ravenous.  The doctors told me not to because she was overweight, but now she is 4 years old and she grew into her chub and is a healthy little girl who loves broccoli, tomatoes, and soy.  As long as you're not feeding you little one junk at an early age, I think they will be fine.
