he has been looking for more milk after almost every bottle a few weeks ago he was only drinking about 3oz in the day then an hr & a half later he would look for more so mw said to get bigger teats & give him an extra ounce ive done that & he is drinking the whole lot & then got his mouth open looking for more i mentioned to mw about going to the next step up milk but she said no in case he needs it when he is about 3 or 4 months old , i think i got about 3 hrs sleep last night as all he did was moan , i feel shattered & worn out , the thing is for his age i think 6 ounces is already to much so i wouldn,t want to give him an extra ounce . violet xx
