I need to travel 2 days overseas without my baby . How to deal if I need to pump my milk?understand not allow to take breast milk while airport checkin. Please advise.

Hand luggage you're not allowed to bring in more than 100mls, you can pump after you've passed custom and security, and when you land, put it into your checked in bag (I.e. The bag that goes under the plane). Although be careful if you're transiting through another airport, you may have to go through security check, and if you're carrying more than 100mls they will make you throw it away. Hope this helps
