i noticed Daddledoo is having four weeks of sales thi smonth (just before Ms Daddledoo ahs her baby), so look out for that.

if your relative buys
- starbunz (sewn in absorbency with optional pocket if needed)
- daddledoo (price includes a bmaboo trifold)
- genesa forge (price includes a snap in bamboo booster
- blueberry (sewn in absorbency)
no bamboo trifold needed to buy extra. except if child needs more absorbency than the starbunz aio style offers (it's a hybrid).

the concept of inserts in ANY pocket nappy or pocket trainer is that you can use ANY trifold, as long as it FITS.

the trifold, when folded in three, must be AS WIDE as the NARROWEST part of the nappy e.g the crotch.
so if the itti bitti trifold fits that criteria - well and good.
but bear in mind, the itti is a narrow crotch style nappy.
their trifolds are not as versatile, when used in other brand products, as the three sections are pretty well divided - like a prefold. this works GREAT in an itti bitti nappy, but won't suit other products UNLESS they are the exact same width.
whereas a TRIFOLD that has no panels sewn down, is just a rectangle, that you can fold as you wish. the trifold is the most flexible option, cos you can easily fold it to suit either narrow OR wide crotched products (nappies or trainers).

another option for trifolds, would be the microfibre car cleaning cloths. $2 per cloth. to get comparable absorbency, you would need more of them in a pocket, so that would increase bulk.

have you got any peapods bamboo inserts? they would do the trick.
