Hi! congrats and welcome!
I will be embarking on cloth diapering again this time. did that for both #1 and #2, so no diff for #3. never tried moomookow before. I am getting a few different brands. there is this brand called Adora which is more common in Malaysia (I purchased from onebabyworld). the type I got are bamboo ones, which are supposedly lighter, more absorbent and more cooling.
also purchased from Amazon. cheaper than SG's moomookow, plus the prints are so much cuter!
regarding the various types of diapers, you can check out this link:
