Bit of background, we have her stay one day every weekend, and one night during the week, but she doesn't stay over. She is very close to her mum and she will be 4 next month. She is starting school in September.
Her mum doesn't have a bedtime routine with her, she goes to bed when her mum goes to bed and she sleeps in the same bed. I have 2 boys, 10 and 4, the youngest will be starting school in September also.
When she stays over when the boys aren't here, she cries when she goes to bed, then she throws up. We have talked to her about it and we thought she understood that she shouldn't make herself be sick etc.
She only does this when the boys aren't here, when they are here, she goes to bed with no problems. She sleeps well and has a routine. Recently she had also started to cry when we collect her and says she wants to stay with mummy. Once we drive away she is fine.
I think she is a sensitive little girl and is very bright. But I think she is anxious and her mum is her safety net and I think the change of staring big school is playing on her mind.
Is there anything we can do to help her, her dad is very upset tonight as he thinks she doesn't want to be here and he feels bad that he is forcing her to be here. I think it's just a phase, as my eldest was anxious about starting school and would go to the toilet all the time, I thought he had a urine infection but he didn't. How can we help her?
