Baby Cravings

I've lately understood based on word of mouth and readings, our diet highly affects baby. Too much sugar and processed foods can cause AD(H)D, eat peanut butter and no peanut allergy, etc. Today I've read, Baby's already developing taste buds (21 weeks) and is influencing my cravings! It feels like he's too young to be in control. Or is this a parenting moment - learn to pick your battles? Of course I ponder this while my (single-pregnancy serving) strawberry banana oatmeal crumble is baking in the oven. :-D
