Am I using the Haakaa wrong???

Kayleigh

Hi everyone, so I got a haakaa as I had heard so many good things. I’m having a hard time with it. I have only ever gotten one to one and a half ounces with it.. and it leaves my nipple very sore and almost swollen. Am I getting too much suction or just not positioning it right?? I have tried google but didn’t find anything helpful. Help! I would love to store up milk without using a traditional pump if I can! Thanks in advance.
