It get worse when they start getting older and peeing more. My advice is change her right when you are going to sleep if she's wet. Try the goodnights but they don't fit small babies, they are made for like 35 to 40 pounds. My little girl only weights 22 pounds at 2y/o so I'm at a loss. I have also tried putting on of those plastic panty type thing on her on top of her diaper too no avail it made a bigger mess. So now I just try to limit her milk intake when it comes down to bedtime and I also just have one of those waterproof bed liner that have a soft top part and just a warm blanket. She did have her beautiful bed spead and sheets but I'm not washing that almost everyday. I with you on the diapers. HeHe I've been tempted to see what would happen if I put two diapers on. One other suggest I could give you is too change her diaper size up one for the night. We buy sizes 3 for day and 4 for night. The huggies supreme work too. Hpe this helps,

ps consider yourself lucky my daughter didn't start sleeping thru the night until she was almost two !
