I can understand why he doesn't want him to have a dummy, I was adamant that I didn't want Shaun to have one (it lasted about 5 minutes) and if he's not seeing how distressed Lewis is then it's easier for him to stick to his guns. It is recommended that babies over 4 weeks old have a dummy at night though, as it reduces the risk of SIDS. It should be somewhere in the leaflet the midwife would have given you about SIDS. You could try winning him over with that? I weaned Shaun off his at a year old and it wasn't too bad, he was just fussy for a night or 2.
We got 5 hours sleep last night, which was amazing after him being awake from 9am until 10:30pm. He's still spewing as much though.
Emma, do you want some Infant Gaviscon to see if that settles Lewis? It worked wonders on Alex for the first week or so. I reckon your doctor will just give him that anyway, it's always the first thing they prescribe when Reflux is suspected.
Are you doing the nights on your own now John is back at work? It doesn't matter the reason, being up for hours in the night is difficult!
