My lb turns 2 next week but for about the last 6/7 weeks he's been waking through the night about 4-6 times. He used to sleep through completely. He went into a toddler bed about 8 weeks ago was perfectly fine the first week and half then he started constantly getting in and out. Now he's in and out four/five times before he goes off then within an hour or two he wakes and so it goes through the night. He shares a room with his 10 month old brother who sleeps straight through but is now been woken. So I have two grumpy boys! Anyone been through this or have any tips?
