Baby Is Picky About Bottle Type

My almost 3mo will only take formula from the newborn bottles that come with the Luna Motiff Breastpump. The nipples are small and narrow. He WILL NOT accept any bottle that has a wider nipple base. But the Motiff Bottles are only slow-flow for newborns. I need nipples with higher levels of flow. Any suggestions for bottle with similar nipple types? Thanks!
