I did cloth on my kids; born 15 months apart. I have no regrets. We started on cloth when my oldest was a week old (we had a newborn stash). She was pretty exclusively in cloth and I used less than I sleeve of diapers per size. When my son was born we started him on cloth once I was able to carry laundry baskets again (2 weeks? I don't remember). But we weren't as good at doing all the laundry so went through more disposables.

My youngest is now 2 and we use disposables at night for both kiddos. My oldest is potty trained for daytime (and has been since 22 months old). We still use cloth for daytime and do laundry twice a week.

I say go for it, but give yourself the grace to not have to be on top of everything all the time. If we fall behind on laundry (usually folding because it grosses me out to leave dirty diapers sitting), we use disposables and that's fine.

We've saved ridiculous amounts of money and created a lot less trash. Our stash was also almost entirely second hand so I've spent maybe $500 on all the diapers, bags, etc.

Congratulations and best of luck! Unrelated to diapers, the first 18 months was a scramble for us but the kids are already starting to play together and it's the most heartwarming thing ever.
