Ex and I split when DC2 was a small baby, DC2 has a rare disorder that would make childcare incredibly challenging and I would mainly rely on the support of my family. I made a choice when DC2 was born that I would be a SAHM, but obviously with the split this isn't really doable.
I have been looking for 2/3 days work a week for the time being, my DParents have said they would care for the DCs 2 days per week (retired), and ex would cover the other. He has until now had one weekend day and one weekday.
He is now saying he cannot possibly "give me a day" reliably as his rota changes all the time. He works in a sort of sports centre, so I can't see how it is "impossible" to ask his boss for the same days off because he has DCs.
At the moment I am really flexible when he makes last minute changes to when he sees the DCs as I am able to be as a SAHM and largely home (on account of DC2), but I don't see how this can continue long term and it just looks like he can do as he pleases and I will just take the hit financially and emotionally with the DCs until school?!
