My 4 month old little boy Ciaran (spirited) has never been a great sleeper. From the beginning he slept for long stretches but never consistently and naptimes were a nightmare. We finally put him on E.A.S.Y about a month and a half ago he was able to go at least 5 hours a night with no feed, we've just put him on a 4 hour schedule which is working beautifully for the daytime. He is actually eating during the day now and he is sleeping about 2 hours (he used to sleep no longer then 45 min) with a little help from us at least one nap a day (the other nap is a major struggle, but we've only just started this about 4 days ago and I suspect it will get better).
The problem we are having now is that he will not sleep longer then an hour a night without waking up and calling us. Before I started him on 4 hour E.A.S.Y I thought it might just be a growth spurt so I was feeding him every 2 hours or so. He wouldn't eat so we put him on the 4 hour schedule and the first couple of nights he slept almost all the way through, waking maybe at 4 (which I fed him) and then at 7. Then all of a sudden the last few days he's been waking up every 2 hours or more, and we've been patting him back to sleep, which only takes a couple of min, but then he's up again an hour or so later. Last night was the worst and he was up almost all of the night. I don't want to feed him, because I know he's not hungry. He's not really crying, just fussing, but if you leave him for about 20 min he's all out screaming.....but a couple of pats and he's back to quiet....though not sleeping......

Our routine is normally like this:
7-7:30 up and feed
7:45 activity
9-11 nap
11:15 feed
11:30 activity
1-3 nap (this has been the harder one the past couple of days)
3:15 feed
3:30 activity (we've been leaving the house at this time and running some errands)
5-5:30ish nap (this has been in his car seat the past few days as we've been out)
5:45 feed
6 activity
7nightime wind down (bath, song, etc.)
7:15 feed (not to sleep...he's awake when we put him down)
7:30 sleep
10 dream feed
And then he's up every hour or so. So my questions are:
Am I messing with his nightime sleep by trying to get him to sleep for longer then 45 min during the day?
Should I be feeding him at night?
Should I start him on solids?
Is this just a phase because he's starting to get to the roll over/sit up time and I should just wait it out?

Thank you so much in advance, any advice would be welcome!!
