Just looking for opinions...3rd child, too soon?

I think worrying about "the right time" many people pass up on good situations. My hubby travels....a lot!!! I stay at home but just keeping our house, schedules etc is a full time job. Our first sib set of 3 arrived July and 5 1/2 months later, unexpectedly, we added their 3 bio cousins. All six children were under 7 and special needs to boot. I, at the time ran a home childcare and had 8 fulltime children. We managed to juggle schedules and make it work for a couple of months before it became to much and I quit to become a stay at home mom. We started with routine and structure upon everyone walking through the doors. My days are very much the same. Its the only way that I manage to get it all done. The key is making everyone accountable. Little kids can wash a table, fold towels and gather dirty laundry. etc. We do 15 min cleanups instead of routine chores and much much more gets accomplished with the older children. I plan meals usually on the fly but have an extremely stocked pantry. I bath children like an assembly line and play time in the tub doesn't happen unless it is on a non bath night. As far as time for myself I don't get any unless it is between 8-10pm. I usually grab a book and a tub for myself. I really enjoy my life. It is busy, chaotic and filled with laughter and struggles. My door is always open for more children. Only you know your limits. I think one just chooses to make it happen if you really want to. So go ahead and make it happen!
