Hiya, I exclusively breast feed my 3 month old.
My MIL suggested I try a sippy cup. Initially I thought 'no way, too young!' (especially since the cup ive got says from 4 months)... But now I'm thinking why not!?
She's got excellent head control now and can sit with lots of support (like a bumbo) if that makes any difference.
What do you think? Worth a shot?
