How did you manage your sanity as you managed your fussy, spitty, lovable, adorable little one during the late nights.

I wrote in a post about my son's fussiness how he keeps crying out bloody murder as if he is in pain all the time... Now it's to a point where he is seeking attention. He gives this cheeky half smile but inside it riles me up. I love my son now it's like I am wanting to move to a hotel for a couple of nights just to get decent sleep. I have this huge headache. Being a new mother I am not sure what I am doing at times I just want some sleep at night. Does anybody else go through this and if so how did you manage your own sanity and irritability.
