Awake time in Day 4 Month old

[Mum2Millie]

My DD starts to get tetchy after being awake for periods of 2 hours in the day, then I know it's time for her nap. Just wondered when they start to extend their awake time?

Not for ages yet.
DD started off being able to stay awake for an hour at a time. By 4 months 2 hours was her max.
But she was in a routine by then ... she woke at roughly 7am so was always down again by 9am. She probably did around 3 to 4 sleeps a day then.
She was in a 2 sleep a day routine at 7 months (she could go from 3pm till 7pm if she had had two decent naps by then)
At 12 months she dropped her morning nap and could go 7am till 12noon then 2/3pm till bedtime.

Thanks, that's interesting we are also on a routine very similar, starting the day at 7 and back in bed between 8.30 - 9.00 and so on. I can't complain as she is sleeping through now (7-7) it's just quite restricting going out and about, as she doesn't really like napping anywhere other than her cot!

My DS is six months and has just extended the time between his morning and lunchtime nap and dropped his afternoon nap.

He now wakes at roughly 6.30am, falls asleep during the school run and I transfer him to his cot when we get home and he sleeps in total for about an hour. He then has his lunchtime nap at about 12.30pm for roughly two hours and that sees him through to bedtime at 6.30pm. I'm not expecting him to drop his morning nap until he's about 1 yr
