The babies have also changed in a number of other ways. They've started exploring their cage regularly, and a few are even running on the wheel. Probably one of the biggest changes is that they've all started eating solid food; both the puppy chow and the regular rodent diet seem to be popular. I'm sure Rem is happy about that ...

Even with all these changes and new behaviors, the babies will still sleep on our hands :)
