DS settles himself and naps well in the day 9-9.30 and 12-2 like clockwork. He was sleeping through 7-7 from 6 months for a month or so then he started to wake at night anything from a grumble once a night (that's less often) to more regularly waking 2-4 times a night sometimes settles easily by being tucked in other times is cuddles to sleep or until he's calm.
Is this normal? (please be honest). DS1 slept through 7-7 at 6 months after an initially bad start.
I'm knackered (but know from experience with DS1 things could be a lot worse), and am at a loss on why he is waking.
