I didint get anything smaller than 000 for DS, and have been given 1 thing in a 0000 for this bub.
Based on DS which is all Ihave to work with, my baby wont fitin 000 for much more than 6-7 weeks. If by chance I have a smaller bub I'll get DH to go out and get some things in smaller, and the 000s can wait til they fit. If I get a whole stack in 0000 and have another very long baby, they'd not be used (by us anyway)
