Great! Thanks for clarifying about the dummy. What i'm not sure about is that when he wakes in the night, putting the dummy in instantly stops him crying, so we don't really need to shh pat, but then he can be awake again 20 minutes later? Is the dummy causing the issue? It's confusing because at other times, both day and night, the dummy will drop out after he's fallen asleep and he doesn't wake up for hours?
We've actually had a big break through in the last 3 nights, he's not waking before the dream feed, and he's then going until at least 2/3am until next feed without any settling, and then through to 6am! I can't tell you the relief after nearly 4 months of being up every 1/2 hours at night!
I think extending the A time has definitely helped, and seems so obvious as soon as you said it! He can't quite handle 2 hours, so we've gone for 1.45, he's still waking after 45 mins during naps and sometimes I can resettle him, other times not, so we have to do some adapting! It just so hard being on the go taking DS1 to and from pre-school etc he's in and out of the car or the buggy all day.
His reflux has also improved in the last week/10 days so perhaps that's also helped with the nights as you suggest, we did have the crib inclined but he seems to be coping much better.
The other thing i'm not sure about is the 6am feed, he empties one side and then falls back to sleep. Should I be starting his day at 6am, or allow him back to sleep? I have let him stay asleep the last 3 mornings after that feed and he's then woken at 7.15/30 which works quite well for our routine of being out of the door at 9am for DS1 pre-school run. But he won't feed again after 6am until about 8.30am which I think affects his feeds and naps for the rest of the day, should I try shh pat at 6am to get him to 7am to feed and start his day then?
