hi...my lo is 10weeks old tomorrow. up until now he's been a good eater and fed every 3hrs but the last couple of days he showing the hunger cues but when you offer him the bottle he starts to cry and won't have it. he will eventually have some but this will take a couple of hours. he'll then nod off for a bit and then start with the hunger cues. he doesn't have a temperature. I'm at a loss really. any help would be greatly appreciated
