P.M.
Small children will always choose sleeping with Momma over sleeping alone in their own dark, isolated and scary rooms. Children crave and need skin to skin and cuddling to make them feel confident and safe - and there is nothing wrong with that.
I've bed shared since my daughter's birth... she will be 5.5 years next month is is excited to be getting her own bed and room now. She is ready, no crying, no problems of transition... this is something we were waiting for her to attain and now that she has, I'm happy for her.
Not directed at you per say, but I really wish more parents would but their children's basic needs above their own. America is notorious for pushing inferior nutrition, pushing forced early independence, force wean if they breastfeed, and don't like to give in to the basic biology that rules the human race.
