Yikes 4 hours is not enough!

He will grow out of it but you need to do something in the meantime, can't go on like that. It's hard to get the energy to do anything when you are exhausted. Once we settle back home I will need to bite the bullet, DH won't put up with much more, he is sick of me being in a bad mood about her sleep. She is taking over an hour to feed to sleep at bedtime, I was in the foulest mood last night when I finally got her to sleep, put her in the Portacot then she immediately woke and stood up screaming, so I had to start again.

Have you read the book yet? I looked back over the diary I kept before I started and she was waking 7-8 times on average, got it down to 3-5 pretty quickly which doesn't sound great but a big improvement. Even if you can get one 3-4 hour sleep out of him, it makes a difference ( I used to go straight to bed when I got dd to sleep to clock up as much as possible early in the night)

Hope you manage to keep your sanity a bit longer and get some shut eye :-)
