Just that really.
Last night when he was wailing I turned the monitor up to its higher volume (louder than the actual crying!) and put it next to his ear when he was sleeping and he barely flinched.
I'm going to a hen weekend in a few weeks time and if I leave DS with DH I'll basically be leaving him with no nighttime care. I don't really want DS to spend the night with my parents or anything as we are just getting his sleep sorted and consistency is very important when he wakes through the night. I'm going to have to cancel my plans, aren't I?
I'm sure it can't be normal that DH can block out all sound?!
Any clever solutions?!
