It is HARD. My exH does have them 1 day a week. I spend that day running around like a blue arsed fly. In reality, it's a few hours. Doesn't even feed them. Dc1 has been really unwell this week, and moderately unwell for 3 weeks. Dc2 is having tantrums slthough not a toddler. Dc1 is sensitive and emotional. I have nothing left to give sometimes.
I guess my ex is involved in that he sees them 1 (short...) day a week. I'm the one who wakes up with them, sorts all the meals, shopping, cleaning, washing, Drs appointments, days off when they're ill , order school lunches, sorts out clubs, cleans shoes, takes swimming, cook's dinner, puts to bed, worries about screen time, anxiety, mental health, honewirk, reading, deals with the good times and bad, I could go on all night. While he bangs on about wanting to be more involved, while simultaneously being less involved.
Sorry. Got that out.
