Are me and my husband ready for another kid?

Me and my husband are getting re-married on July 1, 2011 and we only have two 12 year old kids. I'm 26 and he's 28. I first gave birth to both my 12 year old at only 13, so we haven't had a child for 12 and a half years. Is it time for another? We divorced on June 25, 2010 and will get back together in 2 days. Are we ready for more? I think since we're older, we should be ready.
