That sounds completely normal to me for any age child. As long as the nappy hasn't leaked through the wrap it is working! If the inside of the wrap is too wet for your liking you can give it a wipe and leave to dry for the next nappy change, or I used to just keep using the same one for 24 hours before washing (lazy
When Benjamin was tiny he was changed basically every 2 hours, now sometimes I can stretch it to 4 (sometimes even 5 depending on sleep) but then that is a sopping wet heavy nappy and almost dripping.
I've used little lambs since birth, and the size 2's are still working on a very active toddler and I don't actually put any boosters in, but use wool wraps for the breathing instead.
