Our First Booster is a great addition to the First Fern nappy once your baby has grown into needing a little more absorbency. 
It comes with our super soft fleece lining on both sides to keep baby dry and comfortable. 
The First Booster fits neatly into the First Fern to give additional protection without compromise on fit.
The great thing about the First Booster is that it can be used with any of our nappies!
