I agree with whats been said as well.

For my winter baby we used: 2 x 0000 outfits.
4 x 000 wondersuits
4 x 000 full bodysuits
6 x 000 singlets
6 x socks/booties
4 x 000 outfits i.e. tops & bottoms
1 x hand knitted cardigen
2 x knitted beanies

I had to avoid all things with fitted in feet second time around, because both my girls have had huge feet & they have grown out of length & feet first.
