DD started nursery 2 days per week at 9 months. Soon after that she dropped from two naps to one. I did think nursery probably encouraged this as she was the youngest there and all the other little ones napped at the same time, which she fell into sync with! But she handled the transition well so I wasn't bothered at all.
We had months of good sleep but then the last 6 weeks or so have just been awful. She's always gone to bed at 7 but now just seems wide awake no matter what time we put her to bed. I've tried moving bed time earlier in case she's over tired but it's definitely not that either. She's not falling asleep until between 10 and 11pm every night.
We have had 5 or 6 days over this time period where we've been out all day and she's refused a nap. On these nights, her sleep has been amazing! She's gone to bed at 6.30-7 and slept until 8am the next day every time.
I know 19 months seems so early to drop naps completely, but on the days when she doesn't nap she's getting 13 hours night time sleep. On the days she naps, she gets normally between 1 and 2 hours nap and between 9 and 10 hours night time sleep. So overall she actually gets more sleep without the nap.
I don't know. Would it be harmful to her in any way to gently encourage her to drop the nap all together?
