A Babyhawk baby carrier! With it you can carry the baby on your front or side or back, do housework, go for walks, cook, etc, and literally wear the baby for hours without pain or discomfort to baby and to you. Best thing to happen to my parenting since breastfeeding!
Medela Breast Pump!!!! Lifesaver!
Boppy Pillow - can be used to nurse or to lay the baby in on the floor/couch etc and was great for my baby with reflux.
