Hello,
Do not worry about it...my (almost) 14 month old still wakes to eat at night. I am, however, trying to wean him so when he does wake, I make sure that he cannot settle himself. If after 5 minutes he is still crying hard, I assume he's hungry. I then try to give him only one breast (if you're bottle feeding him, try using half as much). If he takes the bink and falls back asleep I don't push the second side, but if he refuses, I give in. Every child is different and every mother has an instinct that can't be doubted. If you think your child is hungry, feed him. My parents were convinced that there was something "wrong" with my son for waking a few times a night. Now, he only wakes once, around 4:30, and I feed him because he goes to bed at 6 and I'm sure he's hungry. So, hope this helps, and if you need anything else, just email me because I have SO been there and done that. :)
