no real problem. hamsters are considered a generally-safe pet to be around children (if there is such a thing) but they do bite and crawlers and toddlers like to stick their little tender fingers in cages. i have treated many hamster bites; some pretty deep and painful for the surprised child. hamsters tend to be noisy at night and parents need their rests.
i have baby boy 8 months old is there any problem to raise hamsters in the house?
