You can touch them as much as you like when they are AT LEAST three weeks old.
3 months
hamsters are usually pregnant for about three weeks
If you are talking about how long can a robo dwarf hamster be pregnant then it will be about 6 to 5 months,also NEVER TOUCH THE BABIES, since the mom hamster will EAT the babies. I know, harsh.
about 6 to 8 weeks the sooner the better.
Wait at least 2 1/2 weeks if you don't want the mother to kill the babies.
You can feed the baby hamster and everthing but yyou have to wait till it starts to grow fur.
For 16 days.
I have 2 hamsters and they had a litter of pups they are only 1 week and I touch.... I have even carried them...nothing will happen I hope so I am pretty sure you can touch them
about 5 months
16 to 18 days.
They should start hobbling around a few days after birth. For them to fully walk, it could take anywhere from 1-2 weeks, maybe later. This was how it was for both of my 2 golden hamsters they gave birth. Be sure not to disturb the mother and clean the cage before she gives birth. It is safe to touch the babies after 5 weeks.
You leave them alone. Until they're about two weeks old you aren't even supposed to look at the babies for too long, let alone touch them. If you touch or disturb the babies too much, or at all before two weeks, the mother hamster may eat them or neglect them until they die. After about two weeks you can hold and touch the babies but you have to be careful and make sure it's okay with the mom hamster. At about three to four weeks you are supposed to separate the hamsters from the mother and into their own cage. At six weeks you're supposed to separate them by sex. Some places say it's alright to start selling or giving away baby hamsters at four weeks while others say six. It's really up to the baby hamsters. If they are drinking water by themselves and eating by themselves they should be ready to go.
