Ours used to leak but now that we heat them without the green inserts in them and put them in right before giving to baby...no more leaks!
I use Avent bottles I love them my son loves them
Drives me insane, I hate them. I love the Phillips Avent
So I found out that if you warm your bottle with the green filter and nipple, the heat/pressure will loosen the nipple cap screw. So if you do that, just make sure to screw it tighter to prevent leak. Since I have started doing that I haven’t had a leak from Dr Brown’s bottles
I don’t heat anything when I’m using formula and it still leaks so idk what’s going on!
We’ve used Dr browns for 4 months and have never had an issue with leaks 🤔
I stopped using the green pieces and mine no longer leak!
I’m having the same issue too. On Dr. Brown’s website, it said pressure build up (from baby eating and/or shaking to prepare) can cause leaking. I stopped using the inserts and that helped for a little while, but it started again. I’m switching to nanobebe bottles because they haven’t leaked at all yet, and they have an anti-colic vented nipple that works well for us!
Same here!! We just switched to mam bottles a few days ago. Baby girl had a little trouble adjusting but I think she’s doing better now!
