Do you pick him up when he is screaming? i think the method says you should pick them up and do the patting and shushing with them over your shoulder. Are you patting firmly and Susshing loudly? the idea is the sush must be loud and the pat firm, as they cannot focus on 3 things at once, so the idea is if they are loud enough, they should stop crying as they can't concentrate on the crying and "mummy feed me" haha!
I don't know if you have to sterlise the bottles, but i ahve been. I've got the Pod Sterliser from mothercare for ease. Its pretty cute looking too (for a sterliser!)
How funny, Esme has been down since 7.15 too! Fingers crossed for sleepy babies. I'm going to wake her... well i say wake, shove her on boob, for a "dream" feed about 10 and hope for the best, she has got out of the habit of her sleeping through the night sniff sniff, but hoping she'll get back onto it again soon!
spink afraid i am of no use RE: mastisis advice But, my opinion would be to get checked asap and not wait.
Heron Waking the sleeping baby is a bit of a personal preference topic. i started out thinking, i'd be mad to wake a sleeping baby, and didn't for the first few weeks, but then i realised her little body clock was obviously the wrong way round (day/night) so have since been waking her for a feed if she sleeps more than 3 hours on a trott in the day, and not letting her sleep more than 2 at a time in the afternoon, else she isn't tired for bed time and i'd be up all night. So i guess its what you feel is best, and what parenting style you want to follow! Good luck!!
