My 1st is 5 months next week and once she outgrew her Moses basket before 3 months we've had her on a mattress on the floor in our room, a playmat in the livingroom for naps and currently on a 5 week holiday we've created a mattress out of towels,
didymos wraps and her quilt!
I used a Red and White Indio
didymos wrap and made a pouch with a full french / flat felled seam.
one simple navy cotton
didymos wrap (sling) carseat nappies and bucket (mixture of various cloth nappies) feeding bras, vest tops to make any top into a feeding top.
