Two words for any new parents out there.
WHITE NOISE
Works wonders when rocking, eating, singing, swinging, reading, dancing, bouncing, bathing, clean diaper, not too cold or hot, walking, cuddling, burping, holding just won't quite work to calm the insanely intense out-of-nowhere screams.
We set the radio to the static inbetween stations, turn it up so it is louder than a vaccuum and watch our screaming newborn melt into a calm peaceful babe. So nice! Especially during her fussy (aka scream for no reason time) at night (roughly 6PM-11PM give or take) and during car rides which our baby hates with a passion as well as her car seat. Oy! ;)
P.S. Thought this crying pic fit the topic perfect. :)
