AIBU I have a 14 month old daughter who I co parent very well with my x. I have recently gone back to work full time and the agreement was for his mum to have her mon tues thur fri 11.00 till 4. (Bare in mind in jan she only had her 6 days as I had to get other arrangements)Then she dropped on me on NYD that she can’t do it anymore as she needs to spend more time with her dog, I had 3 weeks to find different arrangements but she still wanted £100 off me as she would have to do 3 weeks so I found a childminder (who is amazing.)the x MIL has visited my house 4 times since she was born and I always had to take her to her nans or her dad would. Now as I’m working full time I spend 2 days a week with little one and want to spend time with her and her nanny is now saying I’m out of order as she don’t see her anymore which to me is her own doing then to top it off she has a 4 year old granddaughter who she went and picked up from 35 miles away and has her staying till Friday when her dad picks her up she see her every weekend and is not charging her mum (who doesn’t work) for the 3 days she is sleeping at hers. I just feel like I’m penalized for working by his mum. I’m now refusing to pay her to look after her own grandchild when the rest of her other children use her for free childcare.
