Pull the syringe back and then give it a little flick, the air bubbles should all go to the top and then you can push them out if that makes sense
As kira said, hold it vertically so the top is up, give it a couple of flicks with your other hand, the air will move, pull down then up and cap off.
Turn it upside down so the bubbles go to the top and then gentle press it to let the air out then continue harvesting. It becomes second nature after a while
Thank you everyone!☺️
Does your syringe come with a lid? I’ve been putting the lid on and holding it down and then pushing the syringe down to push them to the end. Then take the lid off and carefully push the colostrum to the tip.
