Hello Kat,
Your lo sounds like mine right now. For the past little while (2 or 3 weeks) we have been battling going to sleep. The first two naps are okay. I would like to have her fall asleep independently but she needs me to help her fall asleep by pat/shushing. She used to be able to just drift off but now, she is pushing up, rolling over, etc. until she is right knackered and can't settle herself down. It is turning into a huge struggle.
Anyway, our schedule is EXACTLY like yours except that I also feed solids at breakfast. We too, started solids at 5 months 2 weeks. I worry about her being up from 1:30 onwards also. For the past two days, this is the case... after about 1h 30 minutes screaming and pu/pd and pat/shush for her 4 pm catnap both days. If I take her out of the bedroom, she is fine. She will continue on the day, play, eat, etc. But, if I put her back in the crib, the screaming and crying will start again. So, my conclusion is, she is dropping the catnap.
My suspicion on not being able to settle down for naps and evening sleeps is that there are so many developmental things happening at this time. Maybe Alana is experiencing more mobility and this wakes her up or causes her to be more distracted when supposed to be winding down for sleep. I would swear that Arwyn "sleep crawls" as she gets into the crawling position and then can't get out of it, therefore... waking herself up.
I know this post is not very helpful. I just wanted you to know that you are not alone. There is so much going on at this age that I think the little ones view sleep as secondary! :wink:
