Hello! Yes I agree with Hotl re sized nappies to start with. We used a bunch of smalls to start with (plus a few brands made especially for newborns as we still got leaks from the fit being a tad loose on newborn DD) then moved to a mix of mediums and OSFM (one size fits most). We do also have a bunch of sized ones in medium and large. I love the trimmer fit of sized nappies but in many ways the OSFM are a simpler option as you just adjust as they grow, though as mentioned OSFM are often too much for tiny bums and thighs.

We also use night nappies, DD is a heavy night wetter so we need extra good ones. Some people just add extra boosters (the fabric inserts that can be laid over top of / clicked into the nappy interior, even layered with other boosters) to a normal nappy for nighttime use but DD needed an extra heavy duty one.

Speaking of boosters if you go down the track of MCNs (modern cloth nappies) I highly recommend buying some extra boosters. I use mine if we are out and about for a while and for DD's day naps (2-3 hours) as it means you can go a bit longer between changes and avoid leaks.

Also keep in mind any nappy cream with zinc or a beeswax/waxy base (the ones that act as a barrier) will get onto the nappy and affect absorbency as they do the barrier thing and it is so hard to remove so you need some kind of cheap and cheerful fabric that prevents the cream from getting through to the nappy. I just got polarfleece (or was it microfleece- someone might clarify) which is really cheap and cut into strips.

I also buy flushable bamboo liners which make it easy to dump poo in the toilet rather than scraping off. I love them but others don't bother.

We use them full time, washing every 2-3 days (usually 2 but occasionally I forget) and We have about 20-24 on the go.
