• How do I make sure she's not the smelly/weird kid at school - I'm pretty sure she has been (I've already learnt to handle lice/nit detection and removal from both of our hair)?
Agree with the PP who mentioned a trip to Superdrug. Get her to choose a nice shower gel and some shampoo and conditioner. If you've got a bath, maybe a nice bath foam or a bubble bar from Lush. Encourage a bath or shower every day and maybe do something like choosing some face packs and having a pamper night.
• How do you handle homework and overseeing school activities - how much help do you give and/or homework diary checking do you do?
I'd do this daily, one of you needs to help her unpack her bag and check the diary, then see what needs doing for the next day and if she needs help. Is your BF doing the things like listening to her read?
• How do play dates / friendships out of school work - she doesn't seem to have many friends, and the ones she has she doesn't see outside of school, other than a couple came to her birthday party last year?
Could you encourage her to invite a friend for tea one night?
• What do I encourage her to do in the evenings for fun - she tends to either want to watch YouTube, play on the Nintendo Switch, or be my shadow (which I'm glad it's that and not the alternative, but it's really exhausting)?
If she's shadowing you, would she do things like go on a walk, all of you together? Does she do anything like swimming lessons or Cubs? At that age both of mine were pretty into their activities, things like climbing, cubs and cricket.
• She is over-weight (and I know she worries about it) as she's eaten badly in the past - she's had both extremes in the past: not enough food and too much with lots of treats - but what can I do to help with that without making a big deal of it or do I just make sure she's eating a healthy balance of foods? Is it something that she will grow into? I'm over-weight myself, but I hope I model being a larger person who loves their body and knows how to stay healthy in lots of ways while still keeping life fun.
First thing to do is to check with your Bf that she's registered with a Dentisy and her checks are up to date.
She might be better sticking to what she knows for now with food but there's a good guide here on what she should be havingg*. It includes sample menus and portion sizes.
If she does more activity that might help, so do things like encourage your BF take her swimming.
• I've caught her lying, mainly about little things, and I think it's because she used to get in 'serious trouble' when she did something wrong, so she panics and tries to avoid trouble by any means possible. I can see her startle like a rabbit is head-lights when she thinks she's in trouble. I'm trying to be compassionate with her and let her know that things are different now, but any ideas how I can get the balance right between discipline and making her feel safe.
I'm not sure on this one but one thing that I did want to mention is that there is a very small possibility that she could have ASD. It's more likely that she's just acclimatising but lack of personal hygiene, only wanting brown foods, lack of friends and lying can all be signs of ASD.
