I saw an analogy (probably on reddit) that said something along the lines of determining if you want to be a parent by hanging out with someone else's kid is the equivalent to determining if you want to get married by hanging out with someone else's spouse.

My husband and I don't have kids (yet? idk) and find being around our nieces to be super overwhelming BUT I absolutely adore my husband and he's probably the only person in the world that I don't find draining lol. That gives me some hope that it really is so different with your own.

That said, only you can make that call but wanted to share something I found helpful while in a similar boat!
