after I returned to work , with my first, I started finding that nursing would lead to him being frustrated and pulling off soon.
I feared that he was rapidly getting used to the Fast Flow of a bottle.
I insisted the caregiver switch to another bottle (the Adiri Nurser) which is VERY slow flow and a little bit annoying for the caregiver :-) however within days of the switch my son was no longer frustrated with nursing, as it was actually easier than getting milk from the adiri bottle!
p..s I also add in a quick pump before I leave the house-- I find my supply is often best earlier in the morning, and I can get a nice bottle pumped at 7am before I dash out the door.
