My 2 year old pulling down pants

Brooke

My 2 year old daughter has learnt to try and pull down my pants she only started doing it tonight while I was trying to clean my house and my husband was just sitting on the lounge laughing at her while she is trying to pull down my pants and by this time I was loosing my patience with the both of them but mostly at my husband does anyone else's kids do this and is it normal for them to start pulling down pants
