It's a tough one, but I always think age appropriate honesty is the best way to go. I didn't mention the pubic hair when I first found it, just did a quick google and realised that minus other signs it was probably fine so decided to monitor it still feel guilty for not ringing doctor sooner. When I realised she smelled I was helping her into the bath, so I gave her some shower gel and told her she needed to rub it all over because she smelled - not my finest moment, but she was good humoured about it. When I gave her the deodrant she thought it was great because she'd 'smell like Mummy' and evidently I always smell 'lovely', very cute.
Unfortunately I had already dropped her off at school before I rang the GP, and then they wanted me to bring her down straight away, so I was quite breezy when I picked her up. I asked her if she'd noticed she had some hairs on her front bottom, and she said yes, and I told her the doctors wanted to have a look because although it's totally fine to hairs down there, just like Mummy has, it usually happens when you're older, so we needed to work out why she'd got them now. Cue why are we breaking the underwear rule questions from her. She coped really well, but I hasten to add, she is very used to it having had a fair few hospital/health examinations (just not in this area). When the GP said she was referring, I explained to DD that we were going to visit another doctor at the hospital so they could have a look at her too. She asked when etc and said she didn't want to but was quite happy when she realised we'd go and count the ladybirds again (mural at the hospital). Oh to be 5 again!
We've had a few conversations since ie when I've got out the shower and she's announced I don't want hair all over my bottom like you makes me sound like a yeti, and I've just gently explained that it's what happens as you get older. She's also asked if she'll get 'boobies' and I've said yes, but hopefully not yet. We've always talked about how people are different because I've always had difficulties so for example sometimes I use crutches. And she has a great understanding of her difficulties, so she knows why she has to do her physio, and why somethings are more difficult for her than others. I haven't spoken to her about periods yet because she gets hysterical about blood, ridiculously so. So I'm leaving that in the hope that it's not something I have to approach until she's more rational older. I hope I don't regret it.
I guess you'll know your DD best and the approach she'll find the easiest - maybe a book might help? I have absolutely no idea how I'm going to explain any tests to her if she has to have them. Despite me always taking her to my regular blood tests since she was diddy, it hasn't helped, and I have no control over her when she loses the plot, which she will. I am hoping the hospital will be able to lead on this, and I will have to find something useful to do with my anxiety because she'll feed off that. And I will be anxious because last time was so awful. My friend is a nurse and reassured me that they will work out the best way to do things.
^ back to wittering again, sorry, offloading my anxieties in the hope that I become more at peace with them (and I'm honestly not usually an anxious person, can't be in my job!).
