Well. We had success last night - Emersyn officially woke up with her wetness contained to her diaper - yaayyyyyyyyy.
I checked the various absorbent layers when I took her diaper off, and while all were wet, none were really saturated - there was still a lot of absorbency left in the prefold in particular, so I am thinking that toddler prefolds will be part of my night time combo from now on. I just wish there was some way to make the whole diaper a bit trimmer, but at the end of the day it's more important for the diaper to work, than to look good.
Tonight.... I think I will try the same combo again - make sure it wasn't a fluke. She had one bottle during the night last night, which seems to be the norm, so hopefully it WASN'T a fluke. Could I potentially have found the combo that is going to work??????
Stay tuned... again.
