My mum ex and I have 1DC. I am the primary parent who works FT, DC is with me 6 nights a week and with ex 1 night (Sunday evening to school drop off). I have requested that ex contribute more childcare wise (my parent has dc after school and I collect them after work). Ex has proposed we both pay his wife (who is pregnant and has 1DC with him already) to collect our child from school until he is home from work. I’m against this as I have no set amount for financial help from ex towards DC and I am very generous towards ex new DC. I have said the situation of paying his wife wouldn’t work for me and I understand if his wife cannot help out with school pick up/ childcare, AIBU to not want to pay his wife to help look after our DC( and not expect her to).
