Re: I hope it's just a stage...and he's not weaning...
I've had this very experience numerous times with my now 18 month old DD. I would get so sad because she kept refusing to nurse, but within a day or two, she would be right back to normal. I believe she just gets so preoccupied with her surroundings that she doesn't want to stop long enough to nurse.
