I try sunburnt but she likes to be independent and mostly pushes me and DH away. She can go a couple of weeks without taking her vitamin d tablets which if course doesn't help but when I try to talk to her about it, I'm 'having a go'. In fairness though, she has been much better at taking the vitamins more regularly, hopefully is feeling the benefit of taking them.
Talked to her about bedtime routine, you can guess how that went...
Thanks for the tip about vit d spray, I'll look into that
