Apologies in advance: long and boring, and I'm typing one-thumbed under napping baby!
She's six months, been sleeping through (roughly 10 to 7) for a few months. Fed to sleep at night, rarely in day. Since Christmas I've been aiming for naps after two hours awake, greatly reducing grouchiness. However, I had/have no idea how to get her to sleep for longer than 30 minutes, though she clearly needs it. If i put her down early she'd play about then get cross - not sleep earlier. The odd occasion I was late putting her down led to horrible overtired crotchetiness. So awake window seems right, but she'd get visibly more tired as the day went on, though still waking after 30 minutes. Very occasionally she would throw me a curve ball and sleep for three hours.
This past week these long naps have become more frequent (4 hours yesterday at which point I got nervous and woke her up!) She's also started a weird crying in her sleep. A couple of times at about 5am, once when going off at night, and then several times 40 or so minutes into a nap, she'll cry out for 10 minutes or so, but eyes closed, not properly awake. Nighttime she just drifted off again, the daytime I've done a dream feed and she's gone on to sleep for hours more.
I don't know where to go from here. The sleep-crying may just be a weird quirk and not last but I don't really know what to do about it. In general I feel like she's not getting enough daytime sleep, but don't know how to regularise her naps - should I be waking her from the new/infrequent long ones? How can I persuade her to stay down for longer than 30 minutes when that's obviously not enough? I never tried to instil much of a routine, just kept an eye on length of time awake and otherwise go with the flow but wondering if that was a mistake? What should I be doing to make sure she's getting enough? Should I be worried about the weird crying wake-ups - or the fact that she'll sleep half the day away if I feed her over those bouts? What's going on with this baby?!
Apologies again. Nervous first timer and terrified of breaking our magical nights!
