I have learned this the hard way. One day at a time. Do not worry about tomorrow, each day has enough trouble of itself own." Stacie's paraphrase :)
Oh Stacie, me too. Our fifth child was born 5 weeks ago (hence my absence here!) and has it ever been an adventure in trusting my God. I have to abide in Him and not carry the weight myself or I get a rotten attitude! He is faithful.
