My 2 y dd has started fighting bedtime and waking up almost every hour at night. This has coincided with starting nursery for 3 days a week morning sessions. I'm currently pregnant and it's exhausting. It takes about 10 mins of her crying to get her to eventually settle but she still stirs and cries and she's also got a cold at the moment which doesn't help. Is there anything I can do to prevent these hourly wake ups?
