Breast is best. However, I've heard of ppl saying there's really good formula too. Personally I'm dying to breastfeed! I'm excited about it too. Plus you can pump if baby won't latch.
Breast milk saves tons of money
Lasts longer if it needs to be stored
Healthier for you and baby
Decreases risk of breast cancer
Boost baby's immune system
Burns your calories
Saves time
Portable lol
Creates special bond for you and baby
Actually cures things like pink eye and other things (i forgot)
I plan on breastfeeding :)
