M is 13 weeks today! I'm going back to work (30 hours a week) in December so really want to make the most of the next month. We are trying hard to get more naps into our day, as he is still fussy and feedy between 6-9/10 pm, and the sleep seems to help.
He's massive: 20lbs this week but the health visitor who was reviewing him isn't worried - he's also super tall and has grown 4cm in the last 6 weeks.
Nightime sleep is a bit all over the place though: we did have a fairly settled 10-1, 1-3, 3-5, 6-whenever going on, but the last week we've had nights where I've got two 3 hour sleep stretches and nights where it's only been 90 minutes!
How are you all getting on with tummy time?
