My mum is staying with us at the moment. She's staying for 6 months while she's having some work done to her house.
I have to work every weekend for childcare reasons so DH looks after the DC ages 7 and 5. I have said quite a few times that DH does not seem to do much with them and have confronted him. He will take them to the cinema only if I think to buy tickets the night before, he might take them to the park for an hour. He takes them to his mother's and leaves them there for 3 hours every Saturday afternoon. Apart from that, most weekends they don't seem to do much at all 
DC don't seem unhappy because they just get to play all weekend but I have long suspected that are just playing on their kindles all day.
My DM has been here for 3 weeks. She has made a few comments about DH just being on his phone all the time and not doing much with them. Today I came home from work at 7pm and when I went to speak to her, she just burst into tears. She said DH stayed in bed until 10 am and they were helping themselves to snacks from the fridge when she came through. She said he then took them out for an hour to look at planes. Came home. Put the telly on for the kids and went to bed. She said he got up for 1 hour to ask if anyone wanted lunch then went back to the bedroom and played on his phone for the rest of the day. She said he didn't play with them once and barely spoke to them. DH overheard us and came in. She accused him of neglecting his children. He's now sulking in the living room, saying she is judgmental and a stirrer. He says he has had a hard week, has a cold and he needed a lazy day but as I said he does not seem to do much with them any weekend. She is in her room crying her eyes out saying our dc are lovely children and it is breaking her heart. I'm kind of in the middle. Neglect seems too harsh but i'm leaning more towards DM - he needs kicking up the arse right?
