My 4 mth old twins are being really fussy with their bottles. It started with my little boy. He'll drink the 1st half of his milk fine (usually!)but gets really stressy when offered the second half after winding. We've tried putting him down and waiting til he shouts for it again which sometimes works, as does tricking him by giving him a dummy for a few seconds then swapping it for his bottle. But we end up spending at least an hour trying to get him to drink it and eventually he does but it's v stressful. We've also tried assuming he doesn't want it but then he's hungry again shortly after the bottle's no good. Now my baby girl's started doing it too so it's driving me mad! My eldest girl did a similar thing too and we never solved the problem. Any ideas?
