Sleeping through the night

Liz
My little one was born on December 1st and was doing good at sleeping through the night for awhile, but the past couple months she is waking up through the night. Doesanyone  have any tips to keep her asleep longer? She is breastfed and hubby and I do not believe in the cry it out method, not saying those who do are wrong, it's just not something we want to do or will do. Thanks!
