hi, my little boy has been in his own room since 3 months and we have been using a monitor to hear him. im just wondering how old babies are when most people stop using them. i say this because he is a very loud sleeper and i feel as though im awake most of the night wth ever little sniffle. he is loud enough now that we would hear him if he shouted out during the night but i dont quite have the courage to turn the bloody thing off. with second on the way i need as much sleep as possible because im just so tired all the time. if anyone can help me...
