Tegan, it is really hard to do these things when you have two. I really wanted Jack to go to playgroup while I was on maternity leave, and we did start going. But as Tom got to old to sleep in the sling the whole time it all became too hard. He would want to sleep at that time so be tired and grizzly, but wouldn't sleep if we weren't at home. So in the end I dropped playgroup and Jack didn't seem to miss it at all.

I think what you are doing is just fine. Both your kids are getting lots of stimulation and lots of love. They have all they need. Tell that mother guilt (and those interfereing relatives) to leave you alone!!
