2. Mateo is curious about everything and is now much more logical with his reasoning. Nico had explained to him very briefly how babies are made: the daddy puts a seed in the mommy and the baby grows in the mommy's belly. Out of the blue, he asks me where that "daddy" seed is. I tell him that it's in the belly. And then he asks me how the daddy puts it inside the mommy. After nearly chocking and stalling, Santi says very matter-of-factly: the mommy and daddy roll around together and the daddy seed goes in the mommy's belly. Mateo didn't accept that answer. I started cracking up and said that more or less Santi was right. Mateo looked stunned and persistent in knowing how the daddy seed went inside the mommy. I was searching my brain for some scientific explanation which would quench his desire without revealing much more but couldn't so I just said that the mommy swallowed the seed!! Lame and sad I know but I couldn't think of anything age appropriate to say. Any suggestions??
