Hi, my baby has been combi fed from birth but over the last two weeks has been fussing taking the bottle. He will push it out his mouth, lick it, close his gums so I can't get it in even though I know he is hungry. He will do this for a good couple of minutes before he will finally take it, finishing the bottle so proving he was hungry! Any ideas why he is suddenly doing this? The test size is right for him as he's not taking ling to finish the bottle or fussing once he's drinking it. Just the initial taking of the bottle he's suddenly being a bit difficult with! Appreciate any possible reasons why people think he might be doing this!
