DS 4 (nearly 5) presses all my buttons and recently I've been losing my temper and shouting at him. I know it makes things worse, i know I shouldn't do it but I just can't seem to stop. I've tried counting and leaving the room but it seems to take forever for the anger to dissipate. I'm taking quite a strong contraceptive pill for my endometriosis and I wondered if that's affecting my mood. DH is amazing and does a large amount of parenting and stuff round the house so I shouldn't be burned out. I have another DS of 18m and he's much more straightforward so far.... Help?
