Meghan Markle and Prince Harry's kids got the attention of the netizens due to their recent family trip.

The Duke and Duchess of Sussex flew to Costa Rica for a family vacation with their two children -- son Archie, 4, and daughter Lilibet, 2. Markle was photographed carrying Lilibet, but the snap raised eyebrows because some felt that the child had not grown since the last time they saw her, which they thought was strange.

"I have stayed out of this 'Rent a Kid' debate, but it's hard to deny that these kids haven't grown and keep changing hair color. It's absolutely bizarre," one commented. Another seemingly shared the same thought and wrote, "Those kids are always the same size. Year after year."

"Oh, surprise, another back of the head blurry pic. The rent of a kid is exactly the same size as the one they used in their Netflix documentary 2 years ago... It hasn't grown one bit. They were using Stassi [Schroeder's] kid as the fake Lilibet..wonder if this is her or yet another rental?" another claimed.

"More sad Sussex sewer squad rubbish. How does a half-African American child [go] from brown to red to blonde straight hair? The child changes size that is not in line with her age," a fourth person added.

Meanwhile, most supporters ignored the speculations about Prince Harry and Markle's children. Instead, they were happy to see Lilibet again. They were also pleased to see the Sussexes with their children since Prince Harry and Markle have been very private regarding Archie and Lilibet and rarely step out in public with them.

"Thanks for sharing! Nice to finally see them finally being parents!" a fan wrote. Another added, "It's lovely to see that the family have all gone away together."

"Awesome pics," a third netizen wrote.

"That's a relief. I started to get worried about those kids. I really hope they are well," a different person commented.

Some also seemingly shaded Prince Harry over his security battle in the United Kingdom. The Duke of Sussex wanted 24/7 protection in his home country because of the alleged threats toward his family. However, they were able to travel overseas without the same protection.

"That's funny because they're crying about security in the UK yet travel everywhere without crying about security," one wrote.
