So we have been thinking about the whole solids issue recently.

I have no desire to give DD solids before 6 months (she is just over 5 now) but want to be prepared etc.

So do I HAVE to start her on solids at 6 months - where does that magic number come from? Will she suffer developmentally if she starts solids at 7 months, or 8?
Is there a problem with being exclusively BF until she has teeth (none yet )?

She is interested in what we are doing, and loves watching me eat, has always seemed to get hungry/ier when she can smell food, but I dont think this equates to her wanting/needing the food just the experience of what we are doing...iykwim!

So I suppose the question is does she need solids at 6 months if she is happy BFing?
TIA
