bugs at 2, knives at 6, fire at 10 (years not months) Unless he is delayed in intelligence or maturity.
Screaming kids like to be moved rythmically and ear-plugs are a good idea (not for the kid - for you). Pick the kid up place their head on your shoulder (right next to your - now plugged ear) and walk around. Don't squeeze but lightly pat on the bottom until they throwup voluminously into your hair. Then they will giggle and fall asleep for ~10 minutes and wake up screeming again. At this point rythmic movement won't work a feeding will be in order. If you don't smell like mom the feeding won't happen. Try putting them in a chair, standing behind where the kid can't see you're not mom, making the bottle smell like mom by squeezing a bit out onto the nipple and placing it where the kid can get at it. If that doesn't work simply put the kid someplace safe where you can listen to the joyful squal and watch the wriggling worm whilst you wait for the mom to return. Make sure you can see and hear the kid at all times. Remember, for the first three months the kid will be making the emotional noise that the mom really feels. The kid is fine but the mom will be post-partum insane. Everytime the kid screams the mom will react. Every time the kid doesn't scream - the mom will react. Nothing you can do will be right.
Enjoy this special time it only last for a while!
