She has always been a pretty good sleeper but just over the last couple of weeks, she has started waking from about 3am onwards. She sleeps for about 1 - 1.5hrs in a day but it makes no difference if she has no sleep at all. I'm wondering if she is waking up because she is cold. I dress her in vest, pj's & socks. She has a blacket but refuses a quilt. Often she will wake up at night crying for her blanket, but can't keep it on her/pull it up to her. What does everybody else put their kids in to sleep, and how do you stop them getting cold? She hates sleeping bags. Thankyou.
