We're going home in a month. I'm worried that they will start talking about potty again ? My mother-in-law always says her daughter-in-law (younger one) quickly trained her child on the potty (6 months old) and we're still in diapers. The last time we went there she kept mentioning it, hinting at it, joking about it ??‍♀️ It made me feel uncomfortable around the younger daughter-in-law. My daughter doesn't want to sit on the potty ? She is absolutely against it, gets really upset when I try to get her to sit. Didn't think it would be so hard to train her to use the potty ?
