Please don't punish her. Try having a conversation with her about the hygene issues and the fact that her younger siblings can find them in the draws etc. Don't make her feel bad or dirty because unfortunately a lot of girls feel like this when they first get their periods, especially if a lot of the friends don't have them yet.

I started my periods at 9. By the time I was in grade 6 there were still no other girls at my school who had periods. There were no facilities at school for the disposal of sanitary items and I used to hide them in my pockets (wrapped of course) and then in my school bag. My mum used to go off at me all the time and call me disgusting and dirty, which while true just made me feel worse. It wasn't until my Grandma asked me why I was doing it and we sat down as 'women' and discussed it that I started to realise it really wasn't anything to be ashamed of and to hide. She even bought me paper bags so that at school it would look like I was throwing lunch scraps in the bin. Sometimes an understanding ear is much more important than a lecture.

I am not saying you are wrong to be angry with your daughter just suggesting that you approch it more as a lets have a chat sweety, as friends than you naughty girl. Explain that even though Emily shouldn't be in her room going through her things she could have put them in her mouth or anything... but most importantly do the "we need a girls talk".

I relaly hope I haven't upset you or come across as saying you are wrong because as I said you have every right to be angry with your daughter, I just remember what it was like trying to make the transition from girl to women and to this day I don't have a friendship with my mum... she is just someone I tolerate for my dad's sake... my grandma who was there to talk to me ans listen to me is the person who has the feelings that should be my mum's.

Please either get a mod to remove this post if it upsets you or pm me and I will delete the content... If I do offend I am very sorry.
