Should I be concerned? 6wk old' massive nap change

[SweatyYetti]

So DD is almost 7wks, our first and apart from the first 2 wks if that she's struggled napping in the mornings.

This week she's completely changed and she is now sleeping both mornings and afternoons, like a newborn should... But for her this is out of character. Is it maybe the hot weather or should I be concerned?

Babies’ sleep patterns change so much in the early weeks, I really wouldn’t worry about it. As long as she is still feeding regularly, gaining weight and plenty of wet nappies it’s fine if she’s sleeping more than she was.

@User52739 thanks!
