Navigating the Emotions of Another "Nibble"

We were recently contacted by a member of my mom's & dad's church in Arizona about a possible adoption opportunity.  It's the dream opportunity for us...a 16 month old girl & her 5 day old brother.  The mother is incarcerated & requested that this church member find a good family for her children.  Because mom & dad have shared our story & have requested prayer as we wait on God's timing, this church member knew of our story & stopped me to ask if we'd be interested.  Of course, Jonathan & I said 'yes'.  But that does bring to light a few other 'stressers' as we call them.  Additional childcare costs, diaper & formula costs, adjusting to being a family of 5 from being a family of 3, sleepless nights as parents of a newborn, etc.  We believe that adopting these children would be SOOO worth it, regardless of the 'stressers' it would bring.  Please, please, please join us & our families as we lift these 2 children up in prayer as they wait to be placed with their forever family (which we hope will be us).  If it is not God's will for us to have these children, we pray that He will grant us peace as we release our grip on this situation & continue to wait for the kids that will be ours...someday.
