Please help...my 6m old DS has suddenly stopped waking up once each night for a feed and now wakes at least 3 times demanding milk. He's a big ,healthy, contented lad and is also eating well during the day. I've established a bedtime routine with a bath/bottle etc and he always goes to sleep well after a feed but it's just this frequent waking which I can't understand. I know it's early days but my DH works away from home during the week and I have a 4yr old DD who is a light sleeper (and an early riser)so I'm feeling weary... Any advice gratefully received.
