We've been trying to figure out why Alex has been needing the oxygen for so long, so we have several tests scheduled to see if it has to do with her sleeping or breathing or swallowing. We just had her in for a "sleep study" where they hooked her up to a bajillion wires & monitored everything about her while she slept. We haven't really gotten the results from it back yet, but we did get some funny pics.
Also, get a load of this random shot of her lounging around after drinking a six-pack of daddy's home-brewed stout. Wow.
