Anecdote is not data and data is not annecdote. But you have one experience and I have the opposite: I am 100% pro tech, showing the kids how to use smartphones constructively, etx. We were controlling what our kids watch to avoid in particular all the modern crap pumper onto YouTube or various American TV channels - and yet our four year old developed serious attention issues. It's not gone but it's MUCH better since the TV is banned to only be on on Friday evenings. Choose your own path forward but I am happy I managed to help my son be a more balanced person, rather than park him in front of the TV just to have my own 'quiet time'. We read more, the parents themselves drop their phones more often - all in all family life is much happier. I just wish my wife would accept to get fully rid of the thing. Spending time with kids is enjoyable, especially when they are not unbearably begging for TV TV TV or can't focus on a thing longer than 20 seconds. That said - not sure what you're going on about breastfeeding but the evidence that it's good for kids is pretty overwhelming. You shouldn't feel guilty if it doesn't work out for one reason or the other, but breastfeeding is a positive for the child.
