Hi all. (Apologies in advance for essay.)
My daughter is 20wks and a champion of the 45min daytime nap! She sleeps well at night for the most part, except when she randomly decides to stay awake for two hours for no particular reason that I can see.
She used to be a brilliant daytime sleeper. When she first started doing the 45min thing she was so unbelievably miserable all the time, then I think her little body got used to it, and she seemed to be a lot happier (coinciding with being put on Aptimal Pepti for lactose intolerance, coupled with the existing ranitidine for reflux). She generally goes for 1.5-2hrs between naps, and this works most of the time, but out of nowhere she'll have a day/couple of days/week where she just can't stand to be awake OR be put to sleep. She has no reliable sleepy signals because she yawns, rubs her eyes, plays with her hair/ears all day long because she's chronically overtired.
I always try to take her out in the buggy for her last nap of the day (hopefully between 4:30 and 5:15, depending on her previous sleep), but most days it takes forever to get her to go. If I dare take her out before the 2hr mark has passed, she won't even attempt to shut her eyes until then, and even THEN she won't go.
And one more thing (possibly the worst thing): NOBODY ELSE CAN SETTLE HER. She will NOT go to sleep for anybody else. My husband has tried and tried but she just screams the place down and is then awake for even longer. We need to work on this as she's heavy and I'm weak :( Right now she doesn't seem that keen on me during the day, probably because she's bored of me and the house. Husband takes the car to work, and we live in the middle of poxy nowhere with nothing to do around us. It's crap but there's not much I can do about that! So I'm stuck inside most of the time with a whingy baby who only wants me for rocking/shhing... Sigh.
All suggestions so far have been wonder weeks (she's technically out of leap 4), sleep regression and a growth spurt. Well, she's been doing this for well over 8wks, so this is an awfully long leap/regression/spurt! She was also doing it when we had cool weather before this heatwave started, but the heat can't be helping at the moment.
Anyway, I'm just glad I found this thread! Reading it made her seem like Rumpelstiltskin - I really feel for those of you who have it a lot worse than me, you have my complete and total respect!
