My 33 weekers are 7 months old now! I can't believe how fast it's going. Dylan is sitting unsupported, and they both have two teeth. Ryan's working on it, but not quite there yet :)
They are HUGE! Dylan is almost 20 lbs and Ryan is 16 or so. Kind of a big difference, but Ryan has always been a bit smaller and he's currently going through chemotherapy for retinoblastoma so he's probably often feeling the nausea and other side effects. His oncologist is glad he's gaining even if it's slowly- rather than losing like some kids.
Twins is hard work... I was cocky and assumed it wouldn't be as difficult since my oldest three were all born within three years, but having two the same age really is different. I am loving every minute of it, sleepless nights and all :)
