We changed my DS into his "big boys bed" a month ago. The first two weeks were an absoloute success. We put him to bed at night and he just went to sleep, occassionally we would hear him pottering around his room but he never came back downstairs.
Unfortunately, this has all changed in the last 2 weeks for some reason and I now have to return him to bed about 6-7 times a night before he will remain in his room and finally drop off to sleep. Tonight I even found him in his baby sister's room where he had woken her up! I was so angry and really shouted at him (which I think is the worst thing to do) but I was so frustrated. Any advice ?
