DS is 10 months old and recently started crawling. I change him on our bed and I know that I shouldn't but I always watch him very carefully.
This morning DS was playing in the middle of the bed after I'd changed his nappy and DP was next to the bed getting dressed for work. I asked DP to keep an eye on DS while I go downstairs to throw away the nappy and wash my hands. Our house is quite small so this must have taken less than a minute. When I was on top of the stairs I saw DS on the edge of the bed. I shouted, DS fell and DP, who had been on the other side of the bed, ran to pick him up.
DP claimed that he'd only looked down for a second and that it was an accident. I said it must have been more than a second for DS to reach the end of the bed and that it wasn't an accident because DP was being careless. If he couldn't look after DS for 1min he should have said so. DP blamed me for being a perfectionist (which is actually true) and said he never does things good enough for me. Surely keeping your son from falling off the bed for 1 minute isn't too much to ask?
YABU - I shouldn't have left DS on the bed / should accept that it was an accident
YANBU - DP should have been more careful or should have told me if he couldn't look after DS
