Some kids do love being tickled and some do not.
I have 3 kids and they all loved being tickled except for the oldest one who is 13 now and he hates being tickled anymore.
He used to really enjoy it and would love hysterically and I can remember his cute little laugh when he was 2 years old getting tickled by his dad and he was so happy.
But now he hates it and will get really mad if you try to tickle him but I'm sure it's just him growing up and not liking the childish things anymore.
His younger brother and sister love being tickled still and I love tickling them too.
I used to think I would hate having kids but after having my first I found I really enjoyed it and still do.
Being a parent is hard work but the joy you get from the kids especially when they are little is so worth it.
