Yes, there is a fan fold to hold the poo. Personally, I used the common Angel fold with a good diaper cover (e.g. Bummis) that holds explosive poo in very well, at the thighs and the back.
Good quality modern cloth diapers would be able to contain explosive poo quite well, provided they fit your baby snugly. One-size cloth diapers may fit baby better when he is at least 3-5kg, depending on the brand. In the first 1-2 months, most babies are still quite small, so traditional square nappies with S or XS diaper cover may work better.
Pocket diapers are those with a pocket (compartment) for the inserts. For pocket diapers, inserts must go into the pocket so that the stay-dry cloth layer is next to baby's skin. Laying a microfibre insert next to baby's skin could cause dryness to the skin as it absorbs moisture very well. So far, most of the cloth diapers I have reviewed are pocket diapers.
If the diaper is a All-in-One or All-in-Two, then there is no pocket; the absorbent fabric is simply laid on top of the diaper 'shell'.
Number of diapers & inserts depends on a few factors:
- pocket diapers: must replace diaper & insert at every change
- Prefolds with diaper cover or All-in-Twos: replace prefold or absorbent cloth at every change; replace diaper cover/shell only when wet or soiled
- laundry frequency: need less if you wash every day
- weather: need more during wet season
- baby's output: need more if baby is a heavy-wetter or poos frequently
- full or part-time cloth-diapering: more needed if full-time
What I prepared for the first few months:
(Note: my boy is a heavywetter and used to poo up to 11 times a day.)
- 30 traditional square nappies, 4 diaper covers, 4 fleece liners
- 10 Small pocket diapers for day
- 3 Small fleece pocket diapers for night
- 12 microfibre inserts, 6 hemp inserts (for night use, combine with microfibre)
(Alternatively, one-size instead of Small diapers may be used. Personally, I prefer sized diapers for a good fit and I plan to use them over several children.)
The above allowed us to go 100% cloth-diapering.
As mentioned, if inserts are still not dry on a rainy day, I simply fold the traditional square nappy and insert into the pocket. Very absorbent and economical.
