Jessikah, I go & have a shower when Zyon screams for longer than I can cope with, or I go check the mail box.. You do need a breather from the crying & babies wont hurt themselves from crying. Pop him in his bed & tell him you love him, but you just need a break...
Usually when I am outta the shower dried & dressed Zyon is either happily gurgling to himself, or fast asleep & I get a break, enough to deal with him if he starts screaming again..
I have found some cooled boiled water in a bottle helps him heaps with wind pain, if you havent tried that already?
I wear him in the hug a bub heaps to, popping Indah in the pram & as soon as I start walking he's asleep & if we get home from a walk & he's asleep I just leave him in it til he wakes up..

I hope he settles soon, trust me it will not last long (once your on the otherside of the unsettledness)....

Zyon slept from 8pm til 12:30, but woke at 3am had a quick feed & slept til 7am, he is in bed again now...
He is usually unsettled from 5pm, til he has his bath around 7:30, but we just sing & jiggle him!!!
