Thanks everyone. I have been telling him I need space, and that sometimes I don't want hugs or kisses or touches, like when I'm washing dishes, or vacuuming.
He's slowly getting better at listening to me. I think the worst part is that when I tell him to stop he will for a second, then comes back. He doesn't understand I mean stop, for longer than a minute!
I am his comfort. Over the years, I have tried giving him a blankie, a satin pillow case, a teddy. He took up the teddy, but only at bed time. And if he wakes at night, he comes to me for snuggles.
We are just reiterating that I need space sometimes, he is ok if he doesn't cuddle me every 2 seconds, I know he loves me lots, and don't forget in 2 seconds after he's told me 10 times and that daddy is here for cuddles and loving too.
