My daughter is almost one and has been a great sleeper/napper for ages. However, she's just started to crawl (she was late with it) and now whenever I put her down she crawls around her cot and will cry. Whenever I go to comfort her, she's on all fours in some weird position in her cot or trying to climb out of it. I guess it's all to do with her new-found mobility but it's really effecting her sleep and mood, and mine too! Anyone been through anything similar? PS, we've just got back from 10 nights in Florida. She was great on holiday and slept through and napped consistently every day and night (she was crawling then too). Could it be connected? Is she suffering jet lag? We got back six days ago.
