We had lots of problems with Huggies. A friend of mine swears by Huggies overnights. We ended up using Pampers. With both girls, as they got to the point where it was almost time to switch to a larger size diaper they would start having problems with wetting through at night. We would be a larger size just for over night and keep using the smaller size during the day (until we absolutely had to switch to the bigger size altogether). It kills me how few diapers you get in the bigger sizes, so I try to wait as long as I can!
Therese’s idea of changing the diaper just before you go to be is a good idea too. My girls have just already got so many sleeping issues that I’m not willing to do anything that might disrupt a good night’s sleep!
