Hi there!
Many hugs and sorry for the tough times! NWs can be very tiring and frustrating! Hang in there!
OK! I may have a few suggestions
...first of all, his easy. Around this time, many LOs have transitioned to 2 naps or pretty close to it. I believe your A times are too short and he wants to stay up more!
....i would push out that first nap. You have your LO going down about 2hrs after being up. That's def on the low end. I would try pushing in 15 min increments and hold for a few days. See if the long naps continue (which should) ...many suggest going in smaller increments but I think 15 is easier but of course, mom knows best. So instead of 2hrs try having him asleep by the 2.15 A time mark.
This will help push his day forward and eventually push out that last CN out and your just ending up with the 6-7pm BT. If I read correctly, you have a CN from 4:30-5 then BT at 6:30pm? You definitely need to push those A times
....he's waking UT. For the next few weeks I would work on extending A times. Not all at once but little at a time; gently and allowing baby to adjust without becoming chronically OT.
He will have some OT and that's inevitable but in time will adjust
hope this helps!
When u said he eats every 3/4 hours did you mean during the day? Or nights? Have you already. When solids? That many NWs can also be due to some kind of discomfort? Sometimes new foods can disturb tummies
...how many times are you doing solids?
Teething too is common around this time but I'm sure the medicine helps that. I'm sure the rash plays a part too with discomfort! ...I think once the rash passes I would consider the rest. Hopefully that passes soon as it could be a big issue too for NWs
Hugs!!! Positive vibes ur way!
