This is my first message, so please be gentle. I have a 4.5 month old son who used to tolerate all sorts of noise whilst asleep, but over the past month he has become a very light sleeper and wakes when he can hear people talking, the TV, neighbours running up and down stairs, etc. He wakes screaming and unless I get in there quick to calm him down, he'll scream for what seems like hours! Husband and I are now talking in hushed tones, the TV is turned down low and I nearly always blow a gasket when the neighbours start running up and down the stairs at 10.30pm (how on earth they've got the energy at that time of night I don't know!) Would like to hear from anyone who has experienced this prob and how you solved it?
