This is an SO problem

I just feel that a boundary is being crossed here! So my partner has ss 50/50 we also have an ours daughter my ss (7) is exposed to an extreme amount of screen time my daughter is 13 months and I haven't ever had her watch anything ( I'm not bragging or trying to be superior but this is just how I parent her and we've both agreed on this), I don't mind some harmless TV shows in the future but I am careful with it, my partner is always on his phone these days and completely disengaged he works really hard sometimes 12 days on he trot but when he is home he doesn't say things like "oh let me bath her let me have I'd like to hold her you go take a break etc.", I know men need to be reminded sometimes but I feel like when i ask him to do anything with her he is reluctant almost like it's a favour to me, he is generally really great but I also help with ss alot of the time... Now going back to screen time if I do decide he can watch her so I can have a shower or sort my self out I come down and she is looking at a screen it's a boundary crossed and I feel it undoes my hard work and undermines me and what we have agreed on for her!
