I WFH FT at an American company. Which means that I have flexibility around my working hours including working around children (the only golden rule is that for client facing meetings, camera has to be on and no kids).
So all of my client calls tend to be when our toddler is in nursery. I brought up my eldest with a similar set up and it was fairly smooth sailing.
My DH is of the idea that I should always drop off anything from work if our toddler has a tantrum, needs the potty (he's not ready yet anyway), etc... I always tell him that I do my best but sometimes it is impossible. In all honesty I think has only happened once because the toddler got annoyed with his toy trucks.
My DH usually sulks about, but I always tell him that it's not fair on me, and that in any case if he feels SO strongly about it, our DS should go to FT nursery but he should also consider becoming a SAHP as the nursery fees would be higher than his take home salary (once you take commuting into account). He's a bit wishy washy about that point. My salary is currently 3x his, with a promotion coming next year that will take me to 6 figures/ 4x + his salary.
He's reached the top of his salary expectations. We've talked about him changing jobs and such, as he doesn't think he has many transferable skills. He hates retail though which would be the easiest thing to move to
