It sounds like your dive profile, although unconventional and not recommended, was not completely dangerous due to the shallow depths and short dive times. However people have had DCS hits doing the most benign dive profiles, those events are referred to as undeserved decompression sickness, and tend to defy explanation. The key to keeping yourself safe, is taking precautions that lessen your chance of a DCS hit. Drink lots of water the day before and the day of your dives. This is the one key area that most divers tend to slough off and treat with the least amount of respect. It is also the one item entirely in your control that will do the most in keeping you healthy, so keep hydrated. Ascend slowly from every dive. The shook up pop bottle is the best visual description for this. You can open the pop bottle without it exploding in foam, as long as you open it slowly. So ascend slowly from every dive and keep yourself from producing bubbles. Have a minimum surface interval of 1 hour between dives. This is not to say that when you come up from a shallow depth to get a bearing to shore, you cannot go back down to that shallow depth. In that instance you are simply continuing on with the same dive, just make sure you ascend slowly when you need to get your bearings. But after the dive, take your time and relax, stay on top for at least 1 hour. Now onto exertion after the dive. Dont lift weights, run a marathon, chase cats, or go bull riding, and on the other end, dont go to sleep or lay down for the entire hour either. Keep active, but keep it light and relaxing.
Now go out and log some easy dives, and have fun with your daughter. The cherished memories you make will be worth it.
