My DH and I have a friend that we see a LOT (she is also DH's work colleague). The trouble is that the behaviour of her 2yo son is getting worse and worse. Unless he is watched with an eagle eye he will throw/break/rip something, go through all cupboards and fridge and bathroom drawers, batter my plants, trash my 8yo DDs precious things and (worst of all) injure my 2 yo in some way. It's getting to the stage where I groan to hear the car in the drive or ignore text messages in the hope of not seeing them (despite really liking her). I've had to change my house around because of it. My DDs breakables are in the cupboard, out of sight! instead of on the bookshelf and when I know they are coming I race around shoving my DS toys and rip-able books away, and then we have to try to monitor him and keep him in sight for the whole visit, it's bloody exhausting as we see them probably 5 or even 6 out of 7 days a week.
I feel like there's nothing I can do really, my friend can't control him so how could we? Saying something would be both ineffectual and cause bad feeling. How do other people cope with their friends 'wee shits'?
