Nipple size??

K • Mother to a little 🐻... and now one more on the way. Oakland, CA 🌳🌲

Hi all. My 4 month old babe is EBF and I’ll be returning to work in a couple weeks. He fights a bottle so I’m trying to give him more practice before I go to work when he’ll be having bottles of pumped milk. He eats super fast - about 5 minutes on one breast per session. He is using level 1 dr. Brown nipple and I think it’s too slow. Should I move up to level 2 or 3??
