DS started off above 75th centile, but has gradually dropped to below 25th. He is formula fed (SMA, having tried Hipp Organic and Aptamil which he didn't like). He seems generally happy and otherwise healthy, but just doesn't eat well.
On GP'as advice we have changed teat size, so he is getting milk more easily, and are feeding on demand. However, he seems to be hungry, takes a couple of big slurps, and you can hear it hitting his empty tummy - big gurgles! As soon as this happens he starts twisting away from the bottle and refuses to drink more. We wait a few seconds and try again - same thing.
GP and hospital paediatrician have both said not to worry and wait and see how things go - easier said than done! He is our second child, so not a PFB
but my mother's instinct tells me something is wrong. Help! Any ideas of what it could be, or am I just getting my knickers in a twist over nothing?
