My daughter 8 and son 5 are not the easiest. My son used to be very aggressive and is still very demanding and bossy. He was unbearable during lockdown. My daughter has started having lots of strops recently. When their behaviour is challenging, my husband and I start arguing. We live near my mum and the opposite side of the country from his family. We get some help but not loads. He resents where we live and the fact my mum doesn't help as much as his parents do. How can we stop arguing? We can't have a weekend away unfortunately. Any advice gratefully received!
