Right tastes like milk, left tasted like cows milk
My DD said similar! Right was 'mummy milk', left was 'cow milk'.

DD weaned a few months ago, but didn't talk about it or acknowledge it for a couple of months. Then she started talking about how she used to have mummy milk, but now she likes cow milk. It was almost like she had to take a bit of time to process it, and maybe decide if she was done, before she could speak about it.

DS hasn't had a feed for over a week now. He will put his hand on my chest, or play with my tummy skin, but is not interested in actually feeding. It seems wierd, he seems so young. I know many kids don't get to feed til 19 months, but i'm still sad that it looks like he has stopped.
