I know the feeling, my dad has moved in with us and I am terrified of him dropping a pill and not realizing it and when he eats he makes a slight mess on the floor so I am constantly looking. I don't even buy foods that are harmful (raisins/grapes/chocolate chip cookies, etc) anymore because I'm afraid he might drop a little bit while eating. My sons are very well trained on being cautious with the little ones
I usually wait till my dad goes to bed and then get on my hands and knees and look at the floor if anything has dropped
These littles have no idea how much we worry about them!
I pray your baby gets well soon
