For several months, our 19 month old DD has been waking up in the early hours of the morning. We hear her laughing, screaming (joyfully), talking and playing. She is completely happy. This can last for up to 4 hours! We have tried cutting out her naps in the day, and this doesn't seem to make any difference. We rarely go in to her, but when we have, she lies down as requested, but the party resumes as soon as we leave!
Our walls are paper thin and it's keeping us, and possibly the neighbours, awake most nights.
Has this happened to anyone else? We thought it would pass, but has been going on now for several months.
Any advice would be gratefully received.
