Hello!
Well, as you may know, this age comes with a lot of new moments that might start interrupting sleep. Mine was the same at that time and I will share what helped In a bit with us
Teeth, solids, and physical milestones come up around this time and all at the same time it seems
...
Have you begun solids? Sometimes it can disturb tummies and cause nightly discomfort.
Teething... they usually come in pairs as you may know so maybe he's coming on the next one which also causes some pain- i would provide relief before BT like small Tylenol dosage or teething meds if you find teething might be the culprit.
Of course, a new found mobility always causes wakes. They learn to roll and can't roll back. I think hats about when we went through that! He could roll one way but not the other. Sighhhhh ::
Most importantly, let's not forget the beginnings of the 3-2 nap transition too. His easy looks great to me, but maybe as he reaches closer to 6mths, he might need more of a push in A time and slowly start pushing out that CN altogether (on occassion you still will need the CN. Short nap days or EWs etc but ultimately become less frequent) .... here is a link to keep on hand. It is the average A times for ages:
Average A times- BOOKMARK ME! Maybe he's ready for 2.5 A times and ultimately reaching closer to 3hrs by 6.5 mths or so. The best way is to slowly increase one A time, at a time, by 15 min increments. You want to do this for 3-4 days to allow for adjusting. It prevents big OT meltdowns and is gentler.
My experience; when my LO wakes so soon after BT (1-3/4hrs after BT) it was a sign of UT. It would also take forever to get back to sleep. He just wasn't tired "enough" ...as soon as I was able to push out A times over the course of a week, week and a half or so, he was tired enough at BT to continue sleeping. So from my experience I would suggest pushing slightly. See if that works.
As far as your supply, hopefully he's not hungry. That could also be a factor but that's something on your end. I BF as well and I know we had issues when he started having longer naps and going longer between feeds. Also around the 4-5 mth mark. So just make sure he's getting his calories during the day. I'm glad you were able to bring back your supply!
best of luck with nursing!
All the issues that have came up such as his cold etc, it could mean he's just going back to adjusting as well.
Let me know what works! Xoxo
