>>> one of the babies at the smithsonian national zoo is getting comfortable in his new surroundings, bow bow the panda. the public gets to meet him in ten days, but tom costello has a preview.
>> he's a little sleepy.
>> reporter: early morning at the national zoo and bowbow is getting a weigh-in.
>> how much do you weigh?
>> that's more than 17 pounds. after a few measurements --
>> that is like eight and nine.
>> reporter: he gets some one-on-one time with two of her personal trainers.
>> hi. are you going to play with us?
>> try some sweet potato ?
>> so by using this stimulation, it's in essence a reward for her being comfortable close to me.
>> she's now 4 1/2 months old, sleeps about 20 hours a day, then explores her new world slowly and deliberately. with each struggling pull, she finds her way. and like any toddler, she takes a tumble. but despite her name, zoo keepers insist she's strong.
>> she's a mini little tank.
>> this little tank was only about 5 ounces at birth. just last week, introduced to snow in a bucket. in just ten days, she'll meet the public. until then, some extra cuddle time with mom. tom costello, nbc news, washington.
