Baby wouldn't eat

My baby since the day he was born I have to sing or walk around to get him to drink his bottle once I let him be cause I though if he's hungry he'll drink milk but no didn't drink nothing for 12 hours going crazy already he's a year now n wouldn't eat unless he is occupied with some toys n I have to kind force him n then when he has eaten he is running around happy n talking....what am I doing wrong why wouldn't he eat on his own or drink

I've never asked my doctor about this i thought it was normal
