Is this nipple confusion or lack of supply?

Does he take a soother? I ask cause my son will want to 'suck' so he asks to nurse then he pulls off and looks around then goes back on, and then starts fussing cause he's tired. He's 6 months old, when he does this i just let him eat first then i hold him close and put his soother in his mouth and he just cuddles up and is perfectly happy to suck and look around. I don't think that it's nipple confusion, it's good that you keep pumping after he eats because that will atleast keep the supply up incase that's what the issue is. Try drinking a glass of water while he eats, that can help to allow a second 'let down' which might be what he's waiting for (that's why he's happy to eat from a bottle) Your doing what's best for you baby by breast feeding threw these issues, and your doing him no harm in nursing him then giving him a bottle as well if that's what he seems to want.
