We tried breastfeeding. It didn't work for us, for various reasons.
What I didn't expect was the backlash I got for bottle feeding my dd.
When did it become acceptable for EVERYONE to comment on how I feed my child? Did you spend 43hours squeezing her out your nether regions?
No? Then you have no fucking say! 
Regardless of how you are feeding your child, surely if they are fit and healthy, putting on the weight then that is enough?!
