13-14 Month Sleep Regression and Bottle Weening


I have a 13.5 month old son. He used to sleep 11-12 hours a night and has now been waking up in the middle of the night between 1-3am every night for the past month. He whines and needs a lot of rocking and comfort to go back to sleep. I have been attributing it to growing pains and teething. He has 8 teeth right now. I also have been weening him off of bottles (whole milk) for morning and night but he still wants them. He won’t drink his milk from a sippy cup. Only water. Any thoughts or advice would be greatly appreciated.
