This has happened twice to me. A few months ago and last week. He just cried or grizzled when I tried to leave the room. I ended up laying in his bed with him and cudddling him really tight until he fell into a deep sleep. It took a while but for me its easier as he is in his own bed. I kept thinking this better not become a habit as I need my sleep too. But so far its just been the twice. I think its because he is missing me during the day. I know your dd is in childcare too. Have their been any changes at childcare. DS two best friends have progressed to the next room and I think he is really missing them too.

I hope she settles down again for you. Since she is a good sleeper I think she will be good again.

If your DH is like mine he is not much use through the night and to be honest DS prefers me at night anyway. Lucky me ha ha.

Have you thought about a big little girls bed? Maybe she is ready? Just a thought, not to pressure you Having DS in a single bed means there is room for me instead of coming into our bed.
