DS was 3 in August. He was a poor sleeper as a baby, but started sleeping through the night aged about 2. In the past few months, though, he's started waking again, and it can be up to 10 times a night. He doesn't get out of bed; just cries until one of us goes on to settle him, at which point he goes straight back to sleep.
We tried a night light, and he hated it. He doesn't appear to be hungry or thirsty, too warm or too cold.
At my mum's house at the weekend, he slept much better.
DH normally gets up with him as I'm breastfeeding DD, who also wakes a lot. We're both exhausted though.
I've no idea where to start; Google gave me too many options and I got confused (I'm too tired to think at the moment). Any suggestions?
