Shirts can't be sleeveless.
I wear her in a Tula through our journey that includes a train, a subway, a bus, and a walk. I don't want my armpits sweating directly onto the Tula lol, so I must have sleeves.
Shirts with tank tops underneath.
Since I'm still nursing I need to be able to use the two shirt method when I feed her, since I don't use covers.
Shirts with smooth fabric, no embellishments up front.
During the day or during our commute she'll fall asleep on my chest, so I don't want any rhinestones or beading sticking her in her face.
Nursing necklace.
My Vintage Honey Shop nursing necklace comes in handy. She has something to chew on/play with while we ride.
