What tiny babies! I was checking my charts... my Bitsy was 2.3 ounces when she was born... and was 5.1 ounces at 2 weeks.... so a little more than doubled her weight.
I guess your "little ones" are pretty much gaining weight OK.... (for that small). I guess they take after daddy.... (or the hamster

)
Best of luck with them and keep us posted on their progress. Congrats.
