Chatted with my SIL who had milk sippy issues a few years ago. VERY strong headed boy, still is.
She said she had to go cold turkey. No more bottles. It was a VERY hard few days and a long week but he eventually stopped fighting it and took his milk via sippy. She did put all sorts of stickers on the milk sippy and didn't force it. Just kept filling it up and putting it out for him to choose it. He finally broke down on day 2 and had a bit here and there and would throw it at protest after a few drinks etc. She said on day 5 she totally remembers and has a photo of him hiding behind their lazy boy chair, taking secret milk drinks ...like he didn't want to admit he caved and maybe mommy knew best. SHe said yes it was hard but he learned to unscrew the bottle and that was the last straw!
Yesterday evening, HG took the sippy with milk and BA was watching him furtively. Then out of the corner of my eye I saw him pick it up and put it in his mouth. I resolved not to say a word. But I glanced over at him reflexively, he saw me, and pulled that sippy out of his mouth in a flash and threw it! Bwahahaaaa!! WHAT is going on their little minds? He perceives this as a battle that he doesn't want me to win. It's so odd.
Okay last night I caved and gave them their night bottle and then again this morning, their morning bottle (ugh), but I am not giving them ANY bottles during the day. None. So he is going to have to deal with it. I will have to decide whether to go cold turkey again. It is really hard to endure. They are fussy because they are hungry and want the milk, not food. Sigh.
