Need help as struggling a bit. DC1 behaviour can be very challenging. Playdates seem to overwhelm him and result in him behaving pretty badly, being very disobedient, uncooperative, shouting, hitting (me rather than other child), not sharing well etc. If a plate of biscuits is put out he'll just try and grab all of them. 
Obviously I try my best to deal with all this at the time but I am very anxious and it is killing my self esteem.
Despite this there seems to be constant pressure to have playdates from people. Do I just make up excuses each time? Some mums from nursery have suggested playdates and I've ended up not replying which is rude but I just can't face it.
So fed up of having 'the naughty kid' even though other people's kids are not perfect either. So sick of people's comments "X is a bit wild isn't he" I'm doing my best and doing parenting courses etc. I just need a break. Aibu to avoid playdates?
