Im very much a first time mom and learning as i go so i dont know if this is a stupid question or not.😅 My baby boy is 4 months old. Im waiting till 6 months id hes ready to start solids but i also wanted to try giving him a sippy cup around that time as well to see if hes intrested in it. My question is since i breastfeed do i put my milk in the sippy cup or what do i put in it? Is it just breastmilk or is there other things i can put in it as well. Also when did you all start straws in cups? Ive heard a wide range of when babies start on those.
