Yesterday we were at at country park with some friends and my SW11 and two friends with their same age boys. This country park has streams and waterways lots of ducks/swans. No swimming but seen kids paddling etc. My DS and friends go paddling in clearish water less than knee high in a stream/pond that used to flow but in his heat has dried up. Being silly they went deeper until lost their footing and fell. My DS went up to his shoulders the others went fully under v murky brown water. My DS face got splashed from their submerge. Took them a good 20mins to get out due to mud etc but they did and I wiped DS down with some baby wipes but it was another 2hours til he got home and showered off. I blame myself for even letting him paddle. My husband has been so rightly cross with me about stagnant water diseases etc I just feel sick to my stomach. My DS had some scratches too so now I'm looking into all sorts of horrible nasty diseases and panicking. What can I do? Should I take him to hospital? I know I'm looking at upset stomach, infected scratches but what else? I get a bit spiralling at things like this and haven't slept or eaten since yesterday lunchtime out of stress and worry.
