prayer

so, as I'm sure most of y'all know...I'm pregnant again! we've had our first round of tests and everything seems to be going well. I just feel like I can barely handle the two I've got now, how can I handle another one, will three be too many for me? I want this baby with every ounce of my soul, I'm just afraid I won't be good or responsible enough for three. Please pray that I will let God be in control, that I will let Him change me into the mother He wants me to be.
