We're having problems here too. DD was a terrible sleeper but for some time now has been fantastic. But in the last couple of weeks, she's been clingy during the day and waking up multiple times each night. She's 3. Last night she threw a full blown tantrum because I told her she needed to sleep in her bed. She's a kicker/wriggler and me being just shy of 36 weeks, well it's hard enough to get any sleep without toddler antics too! I'm putting it down to baby being nearly here. She's well aware of what's going on and I think this is her way of showing her own anxiousness about it all. Hope it settles for you soon.
