So sorry to hear it’s so hard at the moment, your being a fabulous mum looking for advice In the first place, something that works great especially with little ones is instant reward, I call it lucky dip at work, get some cheap stocking filler bits like lip balms fidget toys a little pack of sweets etc and wrap them up in wrapping paper, pop in box, if they have done amazing work at that time, even if it’s just being kind to one another for an hour, get them to pick a surprise gift and unwrap it as an instant reward xx
