she might be teething and also remember that breast milk its soooo light, so her stomach right around this age is well developed to start eating solid, therefor she feels the need of waking up in the middle of the night! Also what i used to do with my 13 months old baby, is that i would give her water instead of milk because remember that babies can get cavity at such young age because of the sweetness of the milk! so watch out with that! Don't ignore your child, remember that crying is their only way of communicating! I breastfed my child until she was 4 months because i had to start a treatment, and today i see the miracle of breastfeeding, my baby doesnt even get sick thank God, but yeah...you have to start switching milk and solid food...the Dr. will tell you so pretty soon...good luck
