Did you use teenyfits from birth?

I would deffo boost it with something as that will be the problem. Like I said the size 1 bamboo little lambs folded fit perfectly int he pocket and add a hell of a lot of absorbancy. They are also quite cheep to pick up new, and often go for next to nothing on classifieds

Iona has been wearing them some of the time since she was about 3.5 months old (so prob about 4lb 7oz) as they're the only nappies the nurses can manage halfway properly The tabs are crossed right over and could do with being tighter and we do still have leg gape and they are obv rather large on her but they work ok so they would def fit a term newborn.

yep i LOVED them on Darcie when she was tiny, she was born at 7lbs 12oz and they fit right away we moved into easy fits when they started getting snug at about 12 weeks

ETA I boosted with bamboo little lambs from the start!
