Thank you for your quick reply!
Here's what it's been like for the past three days:
W 7.00
E 7.15 (expressed milk + formula for every feed)
A 7.30
S 8.30-10.00 (this is the best nap, goes down OK, needs shh/pat at 45 min mark, sleeps for another 30-45 min, wakes happy)
E 10.15
A 10.30
S 11.45-12.30 (wakes up cranky, yawning, not wanting to eat. I try to resettle with shh/pat for 15 minutes, no success.)
A 12.30-1.30
E 1.30
A 1.45
S 2.15-3.00 (super tired when put down, I try to keep him up longer, but he can't make it since the nap before was so short)
A 3.00-4.15
S 4.15-5.00 (same as above)
E 5.15
A 5.30
S 6.30 (used to be 7 or 7.30 pm, but he is tired by 6 pm, so we start our BT routine then)
DF 11 pm
NW 2.30 am (resettle with shh/pat, reswaddle, paci)
BF 4 am (no formula here)
EW 6 am (resettle same as above)
He used to wake every hour during the night at 3 months, wanting to eat. My milk supply wasn't enough, he stopped gaining weight - so we started adding formula and everything improved. The nights are so much better, but the days are all off!
He manages fine with 4 hour intervals for feeding during the day. His first A time of the day is always the shortest. I tried pushing his A time towards 2 hours, but I don't think he's ready, a specially not with the short naps - or should I push them?
He has started rolling over, so we are now worrying about the swaddle. Should we remove the swaddle? The paci? Oh dear, I can't even think about it..
