Dd, 5 in the summer speaks very well, has done since she was very young etc. The last few weeks, she’s started making words up and speaking sentences in these made up words, nearly all the time.
She’s had a heavy cough and cold for the past week and a half and fever some days, but speaks like this when she seems ok too the last couple of weeks.
Is this a normal thing children do for fun or should I be worried at all?
