Baby is absolutely content during the day, sticks to his normal feeding times etc. it gets to about 4/5pm and seems to constantly fuss and cry. He gives hunger cues, we try to feed him and he will spit out the bottle shortly after feeding for a min or two. Sometimes he goes bright red and screams, we have tried everything to see if he needs nappy change, burp etc but it doesn’t work. He will suck his dummy for 10 mins and be content then suddenly scream again.
