The first thing I bought preparing for the baby's arrival was this chair from IKEA. (I don't think it comes in the same color anymore). It's so nice to have a comfy place to breastfeed my baby! My husband treats that chair as my holy cow.. knowing that I spend hours and hours in that chair, helping me not to develop back pain.
My generous mom used the linnen fabric "Aina" from IKEA to sew me a nursing pillow. I have used that fabric for making other things as well - love when things are matching:)
