Hi, i have a three month old who had at least two BF a night. I have been using greenkids anytime or minky with their inserts and either an easy peasy hemp or PD insert as well, i have never had a leak so far and he quite often wakes with a huge poo that it manages to contain as well. However i guess all babies are different, and what suits one will not work for another. I have just ordered a UDNN as well to try one, so i will see how it compares.
I am new to using nappies overnight, was too scared with my daughter!, i am sure there are more folk here with more experience that can help. good luck
Forgot to say he wears this for 11 to 12 hours.
