Just introduced a pillow for 2 year old. He loves it. But since having it, he’s started waking at night very upset because he can’t seem to stay on it. He normally wriggles down or spins 360. He then wakes upset asking for his pillow. He would previously sleep through unless poorly or teething. He’s recently cut some teeth so I don’t think they’re bothering him anymore (they’ve still got to finish coming through so could maybe still causing pain and causing him to wake but he’s usually fine after this point).
Do I remove the pillow again for a bit until he maybe starts to stay a bit more still or will he soon learn to stay put on it?
