You're sleeping too close to each other! =P
In the earlier time (Back when there were no humans to record this) I sign of biting often meant that the male or female was or is breaking up with the partner.
Have it put to sleep.
Nothing it was just simply scared. its not a sign a tree will fall on you or it will kill you in your sleep =)
When people are in REM sleep (deep sleep) they may be dreaming or they may feel suffocated and strike out at the partner in bed with them. This is normal and nothing to worry about.
You might have bed bugs
No. Not if you and your partner feel comfortable.
If he bites hard he is saying NO! If he nips playfully he is saying PET ME! :)
If he bites you.
If your partner has to go to sleep of course you should turn off the light, after all if you wish to read or something you can always do it elsewhere while your partner obviously needs to be in bed in order to sleep.
If you mean business partner, no. If you mean life partner who is the daughter's parent, yes. If you mean life partner who is not the parent, not unless you name them in the will to be the guardian of your daughter.
Either that your partner was driving the other car or the partner was in your car.
if it bites you you'll die
