- Emily W.Verified Buyer5/5/26ReviewingLong Sleeve Romper 1.0 TOG Bon AppetitRated 5 out of 5 starsBeautiful bedtime onesie
This onesie is lovely. I wanted to get an ergo Pouch onesie as I wanted to make sure I had the right tog to dress my baby in the appropriate tog clothing for these colder nights.
It’s so soft and cosy.
I love the zipper too, makes it so much easier to unzip during the night for nappy changes!
I love it
