Hey darling, I'm going to post even though I'm not an expert at all...so take this with a grain of salt
I am wondering if your LO is starting to need a little more A time (they usually do by about 6 months I think)...The general thing I have found is that a
- 30 minute nap = over tired (very hard to get back down) or gas/reflux pain (also very hard to get back down)
- 45 minute nap = Under tired when put to bed, if they wake up happy and chatty it's probably because they have had enough sleep for now, but usually causes OT later in the day because power naps don't sustain all that well. With our bub 45 minute naps also can mean he has a bm coming!!
If you are keen to have a little more A time just increase it really gradually (ie an extra 10 minutes or even 5 if your LO is incredibly touchy and needs strong routine) and see if it helps, if not you can always go back
I found our LO (who is 12 months) went COMPLETELY awol a little while ago, I was trying to put him down early because he was so tired, but then he wouldn't sleep at all...what was happening was that even though he was showing tired signs he was UT when I tried to put him down, missed his sleep window because he was screaming because I'd put him down to early and then was so OT he couldn't sleep...ouch!! Not good days!! Got it a little better again now though
One other thing I am wondering is if your LO is on the way to wanting some solids, have you noticed he has started taking a real interest in your food, your spoon etc? You may feel it's a little early to start, that's totally your decision, but it does add a few extra calories in the day which can assist during the night
We had to start our LO early (at about 5 1/2 months on peds advice due to his reflux - this is against Tracy's advice for reflux btw.
I hope the mods post for you soon, just wanted to post some support and a hang in there vibe
thinking of you and your LO and hope it gets better really soon
