A friend gifted me some size 2 overnight diapers and I have been using them for about a week. LO is 3 months and *knocks wood* usually sleeps 5-6 hours then another 3, then another 2-3. On a few glorious occasions he has slept 7-9 hours. Anyways, wondering if they are really worth it as I near the end of the pack that was gifted to me. Do you use them? How long does your LO sleep?
