Bedtime.
DS was napping through the evenings. But we are lucky if he has one nap between 6 and 10 at the moment. We have something of a similar situation with DH generally not getting home until quite late. I find that DS wants to spend time with his Dad. DH has come home early today and DS was in the middle of a nap. As soon as he heard his Dad, that's been it. He woke up and has been after attention.
He also isn't going to bed until 10 - 11pm. I've tried making it a big earlier as I've wanted an early night, but he's not had any of it, mainly because he has wanted another feed.
In the mornings, he wakes when DH gets up at 7.30, or when I get him up at weekends at a similar time. I find if I don't, he ends up staying up even later as his feeding times go to pot. He has breakfast then goes back to sleep until about 9.30 - 10am.
TBH I've not given it much thought at this stage about his bedtime. At the moment, he seems happy and it suits us. I'm mindful that our pattern of putting the baby to bed at 7pm, isn't something that tends to be done in other parts of Europe (you'll see babies and toddlers out until 10pm or late regularly in Spain for example).
I figure that he'll change when he's ready, like with the feeding. I think from what I've read, his naps during the day will reduce naturally too.
I think babies have much shorter sleep cycles to adults. Something like 40mins opposed to 3 - 4hours. Even during the night babies don't 'sleep through' as we term it. They repeatedly sleep, then wake and resettle.
I dunno, I think to an extent at this point sleep and babies is almost like trying to fit a round peg into a square hole and our way of thinking about it, is completely out of step.
But then I'm a FTM so I'm possibly spouting bollocks and I am prepared to be told different from someone who knows better!
