My 7 week old son, seems to start stirring at 3-4 hours after sleeping and will then start thumb sucking, but will drift between that and falling back asleep. I unsure whether to get him up to feed then (which I have been) or waiting untill he's properly awake.
He used to wake and cry for a feed and now that's stopped but I don't want to wait to long to feed him if he's hungry.
