Funnily enough I was going to remark to charley on our Junie thread (which you are most welcome to join, Ellieo) that we appear to have identical babies, two little refluxy monsters with no routine, both born on 22nd June. And now I see that our little dses have a third to keep them company - in the sleeping stakes at least
My ds sleeps and wakes pretty much as yours through the night, Ellieo. I have abandoned any hope of getting him to sleep through for a while as he simply doesn't eat enough in the day (for which I blame the reflux). Indeed, I spoke to Welshmum's sleep counsellor today and she felt it would be 'dangerous' (her word) to try and get ds to go through, although perhaps she thought I might be going to try the "ignore him and eventually he will stop crying" method, which I am certainly not going to.
My feeling is he will not sleep through until he starts on solids, although his feeding is picking up during the day now we have him on Omneo Comfort - obv no help to you Ellieo.
My ds weighed 13lb 6 1/2ozs this time last week, just to give you an idea, so I guess nearing on 14 lb now.
Day sleeps - like charley's, mine can only go an hour or so between naps in the morning, although convincing him of that is a different matter! He then has a long nap at lunchtime, between 1 1/2 & 3 hours. A further nap or two in the afternoon and is normally out for the count by 7 p.m. I will note that tonight he is still up though, the little devil, despite wolfing about 8oz in the last two hours.
Hope this helps, there are five of us already on the June thread with babies born on 22nd June, but always room for another!
