Byrony,
I put her to sleep at 6:12pm, which I think was fine but a car alarm outside her window woke her for a bit at 7:25pm, and a few cries at 2:30am, but I didn't need to go to her.
My lo is spirited, and so her tired signs are tough. I think I was putting her down too early when she first yawned or had an eye rub, and was getting 37 min naps. Afraid to extend the A time b/c I feared OT. Now it seems she shows tired signs for about an hour before she'll actually have a good nap (> 1 hour), so that's what I've been going by.
Yes, we wind down before naps.
Today I put her in at 11am for 1st nap after waking at 6:25am, and I think it may be a little early. If she only sleeps an hour, that'll take us until noon, but she won't go for another nap before 5pm, and then she won't go to bed before 8ish. Tonight's bedtime might be 5:15pm.
