Another young mother, who brought her newborn son along to meet the couple, told People, "She said her pregnancy had gone so quickly."
“I asked her how she was coping on those high heels. She said, ‘One day at a time!’"
A woman named Rebecca Blundell, who was in Hamilton Square with daughters Lily, 6, and Lottie, 2, also had the pleasure of meeting the couple.
Blundell says Harry asked how to spell Lily’s name.
“Meghan came up straight after and said that he’s going to be a fantastic dad,” Blundell shared to the publication.
If the new Royal Baby is born in April it could share a birthday with Prince Louis, who was born on April 23, or even Queen Elizabeth who was born on April 21.
This isn't the first time Meghan has hinted that her baby is due in April.
Royal blogger @DuchyOfSuccess noticed that the stones may represent the birthstones of Harry and their future son or daughter.
“I’m hoping Meghan’s stacked rings represent their birthstones and Baby Sussex is an April baby,” she shared on Twitter.
In addition to revealing that she’s due in late April, Meghan also responded to a young fan who asked whether she was having a boy or a girl.
Kitty Dudley, 9, from St Anne’s Primary School in nearby Rockferry, said, “Meghan came up to me and asked me how old I was and where I went to school. I could see her bump and I asked if she was having a boy or a girl and she said, ‘We don’t know whether it’s a boy or girl, we are keeping it as a surprise'."
During their Birkenhead outing, Meghan and Harry visited a number of community organisation including Tomorrow’s Women Wirral, a group that supports women in vulnerable circumstances.
They also took a tour of a Feeding Birkenhead citizens supermarket and community cafe in the town. Feeding Birkenhead is a coalition of churches, food banks, community groups, and other organisations working together to eliminate hunger in Birkenhead. The supermarket enables local families to buy their weekly shopping at a discounted price, and provides advice and advocacy on benefits, looking for work, debt, budgeting, and cooking.
