Do you prefer to latch baby or pump out milk when you are outside and why? I am referring to staying outside like half a day out shopping with baby.

If given a choice, I would prefer to latch outside. It's heaps more convenient because you can always latch on the go. Put on your nursing cover and feed. With pumping, you will need to lug all your pumping equipment and find a nursing room to pump then still need to feed your baby later. Sometimes nursing room is also occupied and you don't have a space to pump, or maybe your baby starts crying when you start pumping. Quite stressful if that happens! So definitely latching is the way to go for me :)
