Anxious 6 year old..

Hi There,

I'm a little bit concern about my 6 year..

But if background - Master 6 has always been a happy, confident, secure little boy but over the lasts few months he has become come anxious about doing things and staying at families houses over night (eg. Grandparents, aunties etc.).. We had a new addition to the family in August and I was in and out of hospital with diabetes and preeclampsia in the last couple of months of my pregnancy..

He says he loves his baby brother and he gets upset because he doesn't want to leave him.. He also started primary school last year, so it was quite a big year for him..

I really hope that it is just a mixture of everything and that it's only a "stage" but can anyone shed some light to if this is just a "stage" or do you think it may be something more sinister.. TIA
