I think that Huggies have deteriorated in quality. We used the NB ones on Jack and had no leaks, by the time Tom arrived the Huggies had changed style and we had tonnes of leaks. I am now using MCN and swear by them. In fact last night I put Tom in a sposie as a one off and this morning he did a big poo and it leaked out the side of the Huggies. I haven't ever that problem in MCN (although I never used them on a nb).

I would switch to using MCN when out and at night, and use up your stash of sposies for shorter wears during the day.
