Whole milk 🐄

So tonight we tried whole milk...a little back story...aria is basically a shitty sleeper 😂 always has been. Shes breastfed and last night, for example, I dont actually know how many times she got up but I know that 1:30am was her 3rd wake up. Im also pregnant with baby #3 so a few months of sleep would be great before it all starts again. She has never had a bottle and the only way she drinks water is in a 360 or open cup. So i go her a sippy and hoped that maybe whole milk before bed and at her wake ups would stop her waking? 🤷🏼‍♀️ I dont no? She definitely wakes for comfort not hunger 🤷🏼‍♀️ but let's just say...she hated everything about it and is currently being breastfed to sleep as I type this 🙄...
