Trouble shooting for the Haberman Suckle Feeder

[KristenLeeD]

Hi!
Anyone have any experience with the Haberman Suckle Feeder? We are not sure if we accidentally warped some of the parts during sterilisation in the microwave, because we are pretty sure we're using it properly. BUT we are absolutely not getting a slow flow. Baby is able to take one latch and suck and the whole thing can then drip through really easily, making a feed super quick just like any bottle.

We breastfed her in an upright position all day with burping and she had absolutely no problems with posseting or reflux, and then immediately after using the bottle with expressed milk, she was possetting and got the hiccups! We thought this bottle prevented all of that.

Advice?

That definitely doesnt sound right, I had a faff getting anything out the teat to test the temperature! They have a good website, might be some tips on there?
