Fingers crossed he soon figures out that sleep is not his enemy. You're definitely not alone - lots of kids this age still do not sleep through.
You could try night weaning and see if it makes any difference. I did it at about 14mo to ttc again. DS was 18 months before he could go all night without eating, however, and up to 2 or so he still had the ocasional night where he needed food. And of course it didn't stop the night wakings. But it might be worth a try anyway
