Separately from that, Eric has really started sitting on his own in the last 2 weeks. It's so much nicer to be able to put him down and let him play with some toys now. He's nowhere near crawling yet and I'd like to keep it like that as long as I can:
Lastly, I love comparing my two boys at the same ages. Here they are, both just shy of 6 months and sitting up. Eric is SO skinny compared to Evan - his weight is actual worrying me right now. And to me, they look nothing alike.
