That sounds like the perfect first walk. Glad she's better too.
When they are very young you are quite safe letting them off lead (so long as you have checked the safety of the location - roads, other dogs etc) because they don't want to go too far from you.
As they get older though, and more confident....well, they do try to wander off a bit. That's why you need to get the recall going as soon as possible.
Our breeder suggested we do a 2 level recall: an ordinary voice recall, with a kibble type treat as a reward. Then for more urgent recall, a whistle with a high level treat such as cheese or frankfurter. We have done this, and so far he's been almost perfect. In fact the other day he was haring off after two dogs when I whistled and he turned in mid-air and ran back with his ears flying in that adorable cocker way! Much praise for that!
We realise that at 5 months he is soon going to turn into a real Kevin, so we are making sure to recall several times during each walk, always getting hold of his collar, commanding a "sit" and rewardeing before releasing him to play again.
Have fun, it's great once you can get them out and about isn't it?
