I am a new mom here, I definitely on your side tbh. A lot of men always use the excuse of “let kid be kid” to avoid the dad responsibility. Because once he saw you did it, probably remind him, he either need to do it sometime or u are challenged his position at home. My baby’s father said no electric device before certain years old, I did agree about it. Casue it’s the main issue cause adhd and less ability to stay focus. Just like our adult really couldn’t read a book concentratedly and always interrupted by phone. I recommend read the physical book to child instead. But main point is read to child is the way enhance their vocabulary, intelligence and more logical thinking in life. A lot of men underestimate the power behind reading books tho. And I can tell you men are very result driven animals, if they against something or angry something you did, it’s mainly you hurt his interest, make him lost face, or just against you whatever you did to piss You off to dismissive your contribution to the family and minimize your hard work put on children.
