Xavier was 2 months old yesterday and we are officially not bothering with wraping anymore. He hates it and you would hear a good 5 mins worth of grunting getting those little arms out. plus the other day I got up in the morning he had managed to kick all his blankets off and was more than happy to sleep without anything, so I don't wrap. He is sleeping for about 9 hours each night, and also sleeps in the I surrender position I love that name.
