Mavis Wegg said "It's wonderful news, they're such a nice couple, so sensible and very natural. I'm really looking forward to seeing them."
Her 10-year-old granddaughter Melissa said she's excited, although she did admit she'd like to have seen a baby girl. She thinks the baby will be called James.
Shane Maxwell said "It's not often you get to see royalty after a baby's been born. In Will and Kate we've found a couple in touch with the younger generation like myself and they're bringing about a more modern monarchy."
Elizabeth Bacon said, "I've not seen much royalty in my time.To see Charles and Camilla so soon after baby's been born is so exciting. It's great that they've here in Yorkshire today."
Prince Charles is expected to receive many more good wishes from onlookers today as he finishes his trip to Yorkshire.
Charles and Camilla will visit Uncleby Education Centre in Kirby Underdale, near York, where schoolchildren on day trips can learn about agriculture and wildlife.
The two will then carry out engagements separately, with Charles stopping at a pub in Burton Fleming to meet locals from the small village who last year were affected by the worst floods in 65 years, and will then talk to fishermen at Bridlington Harbour.
Camilla will stop at Bridlington Spa and visit a fish and chip shop and meet members of local charities and community groups.
Together the couple will then join in the continuing 900th anniversary celebrations of Bridlington Priory before finally stopping at Withernsea.
