We have now got a little girl Bramble as "best friend" for our Archie. Shes 9 weeks old and he is nearly 1. Some tips/advice please!

We've separated them at night with a baby gate but she cries. When would you trust them together all night -Archie has always stayed in kitchen and never cried! As soon as we are up she likes to get into his bed - is this a good idea? He doesn't seem to mind!

Only worry is when playing Archie gets bit over excited although Bramble gives as good as she gets. So we're scared they might get hurt if left alone together overnight without us keeping an eye on them.

Got lots more questions, but that will do for now!!!
