These booster sets are to be used in conjunction with the Tickle Tots 2 shell.
Each booster set comes with two bamboo fleece boosters. The smaller booster consists of 3 layers of bamboo fleece and is used on its own when the nappy is on the smallest setting. As your baby grows the larger booster (4 layers of bamboo fleece) would be used. The smaller booster can snap onto the larger booster for additional absorbency overnight or for heavy wetters.
Each booster has handy snaps to secure it into the shell to avoid sliding.
The larger booster also features a waterproof back to protect the shell (to get maximum use from the shell).
