My DDs dad wants to take her to Spain in the summer holidays. Now I know that this is lovely, but I just don't trust him to look after her properly. He normally has her one night a week and she comes back and her hair isn't brushed, she's in the clothes she went in, I highly doubt she's brushing her teeth when she's there and they eat takeaway every time. He's also not the most responsible person with regards to keeping an eye on her. She's nearly 9. She should probably be responsible for brushing her own hair etc but I suspect dyspraxia so she struggles with things like this. Would I be unreasonable to say no? I don't want to take the opportunity away from her but I'm worried about letting her go. She absolutely adores her dad and he does try his best but he's more concerned with being fun than being responsible. She's also not a strong swimmer so I'd be worried about swimming pools/the sea.
