My LO is currently in Size 3 Pampers. We have been using the Baby Dry ones at night as he sleeps for quite long periods but we are finding that he is still leaking out of the top of the back of the nappy. These are supposed to avoid leakages for up to 12hrs and he doesn’t go without a change / sleep for that long. The sizing for the nappies are fine but I am wondering whether to maybe try the Nappy Pants for night time… Any suggestions?
