I need advice or opinions...my son is 6 months old and he wiggles and squirms when he drinks his bottle. its like trying to feed the Tasmanian devil! recently he has experimented with holding his own bottle which he can for a few seconds. but when he does he is so much calmer! Im starting to think he doesnt want me holding his bottle. btw his squirming isnt from the flow, nipple, or formula...he loves it but fights me. what do yall think?
