Why the pearl clutching over a child in the house? The person even goes as far as arranging possible cover from the in-laws. Even if they didn’t, it is a child and not a ticking time bomb. Obvious idiots getting blind drunk or tripping balls into the next dimension aside, an experienced tripper in a safe environment (ie their home) would be able to handle themselves fine.
Why keep the child out of eyesight at all in that case? Why stay in a house and not just camp in front of emergency department if one is so afraid of life happening?
