So my LO has been in size 1s since about a month old. She is now 3 mo today. I still have two smaller packs of huggies & two big boxes of luvs. However, now that my LO is sleeping 5-6 hrs through the night I'm wondering if I should move up to size 2s. In both huggies and luvs she leaks through when sleeping. The huggies fit her perfectly fine, but the luvs tend to leave marks on her thighs and its getting harder to get the tabs to stick in the middle. Should I use the rest of my huggies during the day & move up to size 2 during the night? Let me know what you think!
