When Big Small (6) was the age Baby Small (2) is now Middle Small (4) was already a sitting up six month old and when Middle Small was the age Baby Small is now Baby Small was born. We having been talking maths of ages and how E is double O's age and has been on the planet twice as long and S is 3 times his age and how E+O=S (early algebra?) and how we need to remember that when sharing and adjust our expectations accordingly.
NB That "Baby" in between O's legs is S's Baby Robert. He's a berenguer and does look pretty real, he has fooled a few visitors.
All of our birth stories are here and are much more readable since Sandra Dodd kindly showed me how to put paragraph breaks into blogger
