Earlier in the day, Milano, 42, tweeted that 10 ounces of pumped breast milk was taken away upon landing at Heathrow. She said in her statement that "breastfeeding my children has been one of the greatest joys of my life."
"Every ounce of milk I'm able to produce for my child is nothing short of a miracle and to watch that milk be thrown away without any regard for my baby, was heartbreaking," she said.
Milano gave birth to her daughter, Elizabella, in September. A representative for the airport responded to the actress's tweet, explaining that regulations stipulate that had she had her daughter with her, she could have kept the milk.
"If you are not travelling with a baby / infant all your liquids must comply with the 100ml rule," the guideline reads. "Spare supplies should be packed in hold baggage."
Milano said in the statement provided by her rep that she didn't blame security at the airport, since employees were "following orders to keep us all safe." She added that she hoped the policy received a "thoughtful reconsideration."
"I'm glad this has started a dialogue," she said. "My only hope is to make things easier for moms, breastfeeding and formula feeding moms, everywhere."
Pumping on a plane is difficult. Small FYI.— Alyssa Milano (@Alyssa_Milano) April 9, 2015
(1 of 2) @HeathrowAirport just took my pumped breast milk away. 10 ounces. Gone. Not okay.— Alyssa Milano (@Alyssa_Milano) April 9, 2015
(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????— Alyssa Milano (@Alyssa_Milano) April 9, 2015
@Alyssa_Milano Hi Alyssa. Unfortunately, without a baby present, the government requires all liquids in carry-ons to follow the 100ml rule.— Heathrow Airport (@HeathrowAirport) April 9, 2015
@Alyssa_Milano Sorry for any confusion caused. To confirm, if you aren't travelling with your baby, milk is subject to the 100ml/(3.4oz) 1/2— Heathrow Airport (@HeathrowAirport) April 9, 2015
