I just got both my Similac and my Enfamil sample packs in the mail. My Drs office also gave me two small cans of each when I first got pregnant. Enfamil sent one small container of formula, six of those individual bottle mix packs and 6 2 oz pre-made formula bottles with a nipple as well as 15$ worth of coupons. Similac sent two small cans of formula, 1 sensitive and one regular and 15$ worth of coupons. I plan to ebf but it is always nice to have something on hand in case of emergency. All I had to do was sign up on their websites and my packages came within 7 days :) I highly recommend just going to their websites and getting the samples even if you plan to EBF like I do 👍
