That's great. Hope you are all getting on well.
How old is your baby now?
Do be careful not to walk him too much. The general advice is to walk for about 5 minutes for every month of their age up to 12 months old, so at 7.5 months old, our Buddy is having 35 minutes twice a day. Occasionally he gets a bit more, sometimes less, but that is the general rule.
This is to help prevent degenerative hip problems in later life. It MAY never happen, but we feel that a bit of caution now will help to prevent a life-time of restriction later.
Wishing you a long and happy life together.
