My DD turned 2 last week. Until now, she has slept very well - we've followed EASY routine since she was 2 months old. She transitioned from 2 to 1 nap when she was 11 months old, her routine since she's been 13 months old has been:
7.30: wake up (I wake her up - half of the time, she is awake but quiet in her room)
1.00: nap. This was 2 hours when she was 13 months but it has been capped progressively (by me, due to her resisting bedtime). In the last couple of months, it has been 45 minutes.
8.00: get ready for bed, in bed by 8.20, asleep by 8.30 (I leave the room 8.20, she falls asleep on own).
But last week, one day, she refused her nap and climbed out of her crib. That evening, same happened with bedtime, she kept climbing out. So next day, fearing for her safety, I removed the side panel from her crib. That day, her naps and bedtime were perfect.
But following day, this pattern emerged: She fell asleep normally for her naps but she doesn't want to go to bed at night and tried various delaying tactics (one more story, go back downstairs etc). Most nights, she fell asleep with me in her bedroom as she didn't want me to leave, but eventually fell asleep after 20 minutes or so.
Her nights have been a mixed of good (no waking) and not so good (2 or 3 night waking, asking me to give her her dummy), but they haven't haven't been terrible (she's fallen back asleep quickly after I went into her bedroom to check on her/give her her dummy). On top of that, she doesn't want to sleep in her bed at bedtime (no problem at naptime) and tends to lie on the floor, until she falls asleep there. I try to carry her back to her bed but she often goes back on floor, so I leave her there (it's a thick carpet + there is a folded duvet along her bed for if she falls, she's often asleep on that section).
Today, she didn't want to go to sleep for her nap (using same delaying tactics as for bedtime), so we had some quiet time in her bedroom for 20 minutes (curtains closed, reading stories, her lying on the floor etc). She's currently out with my partner - I will update this again with how bedtime goes...
There have been changes to her usual daytime routine, in the sense that her usual nanny is off sick, so it's been a mix of my partner & me looking after her + temporary nannies. Activities have been similar, but different people, and I am feeling a little bit of separation anxiety from her - nothing as strong as when she was 18 months and also had a couple of weeks with temporary nannies, but it's there a little bit.
I've been wondering: is it the start of her dropping her nap? But, she's going through the terrible 2s, so this may all be a part of it, her favourite mantra being "no, no, no" these days! She is also going through a lot of changes: started using cutlery properly 10 days ago, started saying 2 words sentences 1 week ago etc So it feels like it's a very busy time for her in terms of her development, so that would no doubt affect her sleep too, I don't want to be too quick at dropping her nap if it's just a temporary thing.
The last 7 days, it's been pretty much "1 day at a time", which I'm really not used to as she has been very settled into her routine since she was 2 months old (we had a few problems then, which is how I came across the baby whisperer and EASY, which fixed everything for us). So it's a bit of a surprise and I don't want to develop bad habits that will harm her sleep long term.
