So my eldest has an inset day at school today and it’s half term next week. DS1 is 5 and DS2 is 2.5. All they have done is argue! They’ve been up an hour and the fighting is driving me insane. I have a 7 week old too so I can’t sit and play referee like normal. I’ve separated them for now but they’re going to have to get along at some point. It’s raining today so I can’t chuck them in the garden (although they’d argue out there too), any hints/tips/way to deal with it from more seasoned parents?
