I’ve been commenting on a few ladies posts that my EBF LO takes Avent bottles and has no problem............

I left LO with my mom for 2.5 hours while SO and I went out for a date (finally after 12wks PP). LO only took 2oz of breast milk from an Avent bottle. As soon as I got to there to pick him up he’s all over me. Rooting, nawing his hands, smacking his lips. He nursed for 10-15 minutes. My concern?? I’m scheduled to return to work in 3wks and my mom will be his daytime caregiver. I’m gonna have to do a whole lot of practicing with him or switch bottles........ 😑 I don’t know what to do!
