I was nodding along to all the mentions of teaching boundaries, bodily autonomy, etc, when it struck me--I "force" kisses and cuddles in my children all the time. But, I think it's different, now I'm not so sure.
For example when my son (10) is upset and I try to pull him in for a hug. Sometimes he resists (I think because he doesn't know what he wants) and I have been known to pull him harder and embrace him, then he slumps into me and hugs back.
Or sometimes my daughter (9) will be grumpy and I'll play a game where I sneak kisses on her neck or arms until she giggles.
To be honest I haven't the ought twice about this. Generally, if they really don't want physical comfort I feel that I can tell, and back off accordingly. Now I'm wondering if I should cut it out altogether.
For the record, we are a very tactile family (which I like, as human touch can be so meaningful and comforting), but we don't force them to kiss/cuddle others, even close relatives. Hmm...
