My daughter has started STTN the past few nights, which is great, but a new problem has arrisen. Currently, she wears newborn diapers and clothes (She was 8.1 at birth and 8.5 the last time she was on a scale, about 3 weeks ago). We change her diaper right before we swaddle her for bed, but 2 of the past 3 mornings, we find she has exceeded the diaper's capacity and her bed, swaddle, and jammies are wet. I hate to come wake her up in the middle of the night to change her diaper (she doesn't like having her diaper changed), but I also don't want to have to wash her sheets every day. Any suggestions on what we can do to stop the night time leaking or do I just need to start changing her in the middle of the night?

We haven't tried other brands, but we like Pampers Swaddlers. They seem to hold a lot of fluid, and I like the stripe that turns blue when she's wet. We haven't had any morning leaks yet. Fwiw our LO was born at 9 lbs and has been in 1s since birth.
