DD is doing the same, and has been for the last couple of weeks. Some days she will not sleep at all or have a 20min catnap and go until bed time.

I was really hoping that it was going to signal the ending of the day sleep was approaching, especially with another on the way, I was hoping she would do it a bit longer.

Not sure how long the weaning off her sleep will take as she has some days she will still sleep for 2-3 hours (especially after swimming), and a few days a week the others is a nap or not at all.

so much for mummy time on those days she doesn't sleep anymore
