ummm.. you don't want to know what I do to
DS if he starts to fall asleep on the couch in the late arvo..
LOL
Last time he did it (last week sometime) I held him up in the air by his foot and waved him around so he would start giggling, and then put him on the ground and tickled him until he had woken up properly and shaken off those sleepy vibes!!!
LOL Or I chase him around the house a bit (well as much as I can in my condition!) and then sometimes I give him something to nibble on to just wake him up and get him through till dinner.
Um so yes, if it was
DS I would definitely be waking him up.
