Yeah there are too many bubs go through this at 3-4 months for it not to be developmental. The W2S worked for us at 4-5 months to get through the sleep cycle just like HTTJ worked for Emma.
Shiv, can you give an idea of what your day looked like then on days when Maeve only took 45 minute naps? How long did you shorten the next A time by? It must have meant 4 naps is that right? Or 3 and an early bedtime?
I honestly can't remember totally but I know I did 4 naps, not earlier to bed.
So it would have been:
8am: Wake up and feed (1.5 hours after good night sleep, at 3 months she slept 10.30 ish -5am (feed) then to 8am)
9.30am: Nap (Generally would have got 1.15-1.30 here)
11am: Wake up and feed
1.5 A time
12.30pm: 45 minute nap
1.15pm: A time
2pm Feed
2.30pm Nap (so overall was 1.15 A time...prob bit long but couldn't do much else with the feed..DD always tried to
fall asleep on the breast at this stage)
45 minute nap
3.15pm A time (this is where it got messy....1 hour A time)
4.15pm Nap (generally 45 minutes again)
5pm Feed followed by A time-1 hour altogether
6pm Catnap (well supposedly!)-sometimes in car, sometimes in DH's arms
6.45pm Bedtime routine etc
7.45/8pm Last feed and bed
10.30ish DF
5am Night feed
8am Wake up next day
The mornings were always better. If I could get that 12.30 nap extended the rest of the day went better. If not it seemed the OT kicked in and that was it for the day. The A time I wrote includes the 15 minutes I would have spent ssh-patting in an attempt to extend too if W2S didn't work. And to be honest as our nights were good I didn't so much mind the naps.
As an aside Emma...have you given thought to how we're going to do this when we have two?!!! I can't imagine DD letting me ssh-pat for 5 minutes let alone 15!!!
