I have followed your routine since the birth of both of my children and they have slept very well up until the few days before we went on holiday. The day before we travelled Rana jumped from her crib and said she doesn't want to sleep so that night we had to dismantle her crib and change her bed into a toddler bed. She was 2 yrs and 9 months at the time.
When on holiday I made the big mistake which is now making my daughter wake up in the middle of the night. I left her to sleep in a room alone which isn't next to me. She would wake up asking for me and although I didn't go to her, she would keep asking for me until she eventually ended up sleeping on the floor next to her bed. This went on for three weeks. I put a gate at her door to ensure she stayed in her room. I realise now that this wasn't a good idea - it made her angry and scared. I stayed in my room and didn't go to her, I didn't even hear her. She would sleep at 7 am, nap for an hour at lunch and then wake up at 1 am till 3 am and then sleep till 5 am. This isn't my normal Rana who used to sleep from 7.30/8 pm till 7.30 am the next morning - we used to wake her up for nursery.
During the holiday we changed destinations and had to put both girls in the same room, both in their cribs. It actually worked well - they slept together and she would wake up at 7 am and her sister would wake up at 8 am. We were in a room next to her and so she might have felt secure to know we are next to her.
When we went back to home, she went back to her crib and asked for us to sit next to her till she fell asleep. She would wake up at around 4 or 5 am asking for us and she would again ask us to sit next to her which we did until she fell asleep. What also worked was a night light and she liked that. However, she has now started waking up again, usually around 12am, 2am and 4am, asking for us to sit next to her on the sofa till she sleeps. My husband does that, but she would then wake up at 5.30am saying she doesn't want to sleep.
On Friday night when nothing was working we tried to put both girls together, with a small night light on but my younger daughter Daneen woke up crying because she isn't used to the light, which resulted in both girls awake at 5 am.
Also her appetite isn't like it used to be before and she has back tracked with potty training. Do you think these are all major reasons for her waking up? We no longer know how to handle her night time waking and as a family we are all exhausted through lack of sleep, all I just want a calm happy family who sleep well at night and are happy during the day. Please help!
