So i got a letter in march explaining my son had been bumped up to go to nursery in april which is amazing. But me and my sons father do not agree on the rota. When we first split he was supposed to see him 3 times a week (mon 7-9, wed 7-9, sun 2-8) but he would often bail or say something has come up and cancel most of the days. Then in february i had to work more and he had him wed 7pm-thursday 5pm but i found out that every thursday hed palm him off on his dad or his sister. So i went to speak to him about having him every saturday-sunday so that my son can be consistsnt with nursery and he flat out refused as "id be just a dad and not have a social life" to which i replied with "look im always a mum as i have him 95% of the time and i dont have an issue with it as thats life" but he refuses and wants to have it weds-thurs one week and sat-sun the next week. But the thing is i dont trust him to take my son to nursery on time as hes already messing up my sons potty training and messing his sleep up. Ive tried to fight for it and he just instantly gets hostile and it just triggers when he used to be hot headed
