Happy puker but not after bottle

[Trixybelle]

I have a 3 month old ebf happy puker. She was bottle fed expressed milk at the weekend and apparently barely puked at all.
I'm thinking now she is just happy and greedy at the boob and is happy to bring up the extra rather than stop when she's full. Or could it be a bad latch? She's not overly windy, and I don't have sore nipples.
I only offer one boob each feed as otherwise it's a tsunami of milk. it's really not helping fend off the 'why are you still bf brigade'

What position is she fed in when bottle fed compared to when breastfed?

If she's more upright when being given the bottle maybe there's just a bit more regurgitation when on the breast because of being horizontal.

She is definitely more vertical on bottle. I've tried sitting her more upright when bf but she's quite tall. Might try some new positions.
Thanks greta.

I had the same problem as mine is quite tall - I ended up with him lying on his side with head/shoulders up on a cushion then hips just on my lap and legs wrapped round my side so his body was at an angle of approx 45 degrees.
