So how do I know when I should move up a size? Right now my daughter has been wearing 1s but we are almost out of 1s, do I buy more of that size or move her to 2s? I’m on the fence because size one diapers go up to 14 lbs and size 2 diapers are 12-18 lbs, at her last doctors visit she was almost 13 lbs so she falls into both sizes according to weight. At the rate she’s been going she gains weight slow. So idk if she will be in 1s for a little while longer or should we move to 2s since she’s in the weight? She’s in both sizes weight wise so just don’t know...FTM here any suggestions are helpful thanks!
