Running Child Upstairs

Hello. I have been living in my condo for 5 weeks. Immediately upon moving in, I realized that the child in the apartment above mine runs the length of the apartment–whose layout is the same as mine– anywhere from a few minutes to as many as 45 minutes at a time. About two weeks ago after having to listen to that for 45 minutes, I went upstairs, introduced myself and politely stated that running for 45 minutes non-stop was jarring and that I couldn’t even hear my TV. The father asked me what he wanted me to do. I told him that the solution was up to him and his wife. I remained polite but clear about the noise being unnerving. He insists on my giving him a solution. I noted that in cases like this carpeting seemed like the solution. He said, “I won’t install carpeting. Anyway, I don’t think it will matter.” I told him not be so negative after pushing for a solution. He wanted us to agree on a schedule. I said, “It’s obvious I’m not home all week from 8 am to 8 pm. However when I come home, I’d like to be able to relax and hear my TV or just read.” He said, “That seems reasonable.” For the most part, there hasn’t been running after 8 pm during the week. The thing is, the weekends are unbearable with that child. I came home on Sunday night around 5 pm and by 6 pm I had to put in earplugs. Ditto for tonight. What would be my next step? He has said NO to carpeting. Am I being unreasonable? Should I stay quite about that noise? Should I just go to the condo association? Try with him again? I’d like to get along with my neighbors but it has to be a two-way street. The only thing, I am obviously the one in the weaker position. Thank you!
