The new parents were chatting to a group of military families yesterday at a coffee morning at Windsor's Broom Farm Community Centre.
During the visit the Duchess shared some details about life with their soon-to-be 6-month-old including the family’s teething experiences and how baby Archie is starting to crawl.
Amy Thompson, whose husband Brad is attached to the Welsh Guards, said: “My daughter Aeris is the same age as Archie and we talked about weaning and the children beginning to crawl.
"(Meghan) is just a normal mum and it was like talking to a friend.”
Prince Harry, also said he empathised with the difficulties of those serving in the military being away from their families and those at home missing their loved ones.
“It's unbelievably hard. I have so much respect and admiration for anyone who has to deal with that,” he said.
Seeing how quickly Archie is growing and developing has given him a new understanding about how families are impacted.
“I can't imagine what it's like to miss so much as they change so quickly.”
It seems that developing teeth and starting to crawl aren’t the only skills baby Archie is developing either.
According to Us Weekly, Archie is not only on track with his baby milestones, he’s actually exceeding some: “He’s a strong baby and you can tell he’s super smart,” a source told the publication.
“He can sit up without support and roll over, and he’s almost crawling. He can’t talk yet, but he’s trying!”
According to Babycentre.co.uk babies usually start to babble from around three months and could start to recognise their name. Parents can expect their babies to start putting together sounds such as ‘ba’ or ‘ma’ from around six months.
It’s only usually from around one year onwards that babies start to say proper words, the site explains.
The parenting site suggests crawling is a skill most babies get the hang of by the time the reach their first birthday, so Archie starting to crawl at six months is pretty ahead of the game.
Last month it was revealed Prince Harry had sent a good luck message to the England rugby team ahead of the World Cup final by sending them a sweet photo of son Archie in a Red Rose jersey.
While Prince Harry attended the final in Japan, which England sadly lost, the Duchess of Sussex revealed to The Daily Telegraph that her and baby Archie watched the match from home at Frogmore Cottage.
And the duchess made sure little Archie was suitably dressed for the occasion in an England babygro.
