DS - 7 mo - has decided to mainly screech for the last 3/4 days. He learned how to make the sound about a month or so ago, practised for a day or two and then stopped doing it except when especially excited.
He's started it up again just before the weekend though, and does it constantly. He isn't unhappy, infact he sits there grinning while he's screaming away. We have tried to ignore him when he's doing it and engage with him again once he is 'talking' in a quieter tone but it hasn't produced any results so far!! Did anyone else go through this, and how long might I expect it to last?
