Thanks all for your advice.
Dear Donna,
Thanks for the offer. I will think about it but at this time I think I prefer a baby hamster, simply because I don't want to disappoint kids with one that might not last long or one that might bite them straight away
My understanding is chances of handling baby ones with kids is better than having an adult one that needs taming. I might be wrong though!
So I will try other options first and I looking forward for any further advice.
By the way, I am sure you are aware of this, but just in case you are not, have you see this:
