at night at least. DD has soaked through everything. Just when I think I've found something, after a few weeks, she soaks it too. She nurses at least 4 times a night. I've had her in disposables for the past week while I searched for my last try. Tonight she is in a nighty newt w/ an Aristocrat soaker. I didn't add a doubler. Hopefully it wasn't necessary. I sure hope it works. I just can't handle changing her clothes and sheets every morning at 4am!!!
