Yes, all 4 sleep with me, or maybe I should say I sleep with them in their nice big king size bed.   
They first started out sleeping in a play pen near my bed, until they could go through the night without peeing.  After that they were welcomed into the big bed.  I did not crate them, in the daytime they were in an ex-pen when unattended.   
For some people, there is a worry that they may fall off the bed and could get hurt, or that someone would roll over on them.  This is more of a worry with tinies.   
It also depends on if you are a light sleeper, and do not like to be disturbed.   
I guess it is an individual decision.        |
