Actress Alyssa Milano took to Twitter Thursday morning to blast airport security. No, she didn't get singled out for a patdown; she had her expressed breast milk taken away.

The 42-year-old mother of two, who has been very open with her breastfeeding of baby Elizabella in the past, was going on a "romantic getaway" without her children and was pumping on the road, something that's important for nursing mothers to do to maintain their supply.

I'm about to go away with my husband for a romantic getaway. Without the kids. Terrified.

Pumping on a plane is difficult. Small FYI.

A few hours later though, she tweeted that security at London's Heathrow Airport took away the milk she had pumped.

(1 of 2) @HeathrowAirport just took my pumped breast milk away. 10 ounces. Gone. Not okay.

(2 of 2) They said they would let the pumped milk through if I had the baby with me. Why would I need to pump if I had the baby with me????

.@HeathrowAirport Why can you test my toiletries to make sure they are safe but you have to throw away my breast milk?

According to Heathrow Airport's website, travelers can carry a "reasonable amount" of breast milk with them, but only if they are "traveling with a baby or infant."

"If you are not traveling with a baby / infant all your liquids must comply with the 100ml rule," the website states.

.@HeathrowAirport I was told I would be fine if the baby was with me. Plus, it was less than 5 ounces per container. Why is my shampoo okay?

Milano said that if she had been told about the size limits on the milk, she would have "happily" poured it into smaller amounts among several containers.

Heathrow officials referred TheBlaze to the U.K.'s transportation department, which sets the guidelines. The airport commission did not immediately respond to a request for comment.

Now, you might be wondering why Milano is getting so upset over the milk if her child is not traveling with her. While breast milk at room temperature is only good for a few hours, if she intended to refrigerate it or freeze it at her final destination, it could last for several days to months.

In the United States, the Transportation Security Administration allows travelers to carry more than the usual 3.4-ounce liquid limit if it's breast milk, formula or juice for a child. These items are sent through the X-ray machine and may undergo other testing by TSA as well. The TSA does not specify if the child has to be traveling with the parent or not.
