Just gorgeous, congratulations
I'm sure you know this anyway, but make sure to spend time with each puppy individually, so they bond to you as well as each other. Some individual walks, playtimes etc.
I'm presuming Dafney is a little girl? Do you have a plan in place for when she comes into season? Boys can be fertile before 5 months so ideally you would have someone able to care for him for about 3 weeks, it's incredibly hard to manage in the home.
Don't forget to build up walks slowly. Free exercise in the house and garden but on lead walks should be 5 minutes for each month of age 1-2 times daily. You can start lead training in the garden. We strongly recommend harnesses as Cavaliers have delicate necks.
Have fun with your gorgeous puppies and we look forward to seeing them growing up.
