Agreed in that, if he WANTS you to comfort him, you shouldn`t have too much farther to go. Most of the time, the kids want mom, only mom and just the mom!!
It is totally normal and rest assured that it will pass. If you think that it would be better for your own child to be elsewhere that day, it probably couldn`t hurt. But you`ll have to do it eventually, so it`s your choice!!
Hang tough my dear!
