DW and I have been using Aldi nappies since DS was born, no issues at all - until now. DS 5 1/2 months and in size 3. DS has started to roll onto tummy during the night, causing quite a lot of leakage from the front waistband of the nappy. When he was on his back the nappy that came off first thing in the morning was always very full but with no leakage. Now that he is on his tummy the nappy is similar weight but is full and bulging right up to the waistband and vest/baby grow/ mattress all wet. Any suggestions/ good brand for tummy sleepers?
