So have a nearly 5 month old who sleeps ok with a dream feed and sometimes another feed sometimes he settles himself bk to sleep.He has a myhummy but have been using Ewan last 2 nights and he doesn't seem to mind it stoppong after 20 mins. I have 3 year old whos quite a deep sleeper but think myhummy would be annoying hence using sheep. They are going to share a room. My husband thinks im over thinking white noise but don't want him to be dependent. I no a few ppl that dont use white noise but dont have great sleepers. Anyway any advice on when to start room sharing and white noise gratefully received! Thanks
