Sarah is on 2 bottles a day (morning/night). The only reason she’s not down to one is because she will ONLY drink formula from her bottle. Just like others have mentioned…if I put it in a sippy she absolutely refuses! Water, juice whatever else she will chug…just not formula! I keep her on the bottles for nutrition only. She is ready to be done with them but I keep FORCING her to drink from it! 
In a few weeks/months/years…whenever I get the nerve…and we try milk I am hopeful to have her off the bottle and on a straw cup. So my goal is by 16-18 months. 
I think Shane is just fine!
Good luck with the goat’s milk!
