I made the decision a very long time ago to let DS wean when HE was ready.

So why last week, without even thinking about it, did I start telling him "boobies are for bedtime"?!
It just kind of, came out. Sure I'm a bit tired of being accosted every time I sit down for 3 seconds, and I'd like him to learn some manners, but I don't want him to wean!
So why am I doing it?
Especially since he's sick with a cold ATM.
Now I feel like I have to stick with it.

(DS seems fine with it, he has been asking, but only when I sit down at home, any other time he doesn't seem to think about it our need it. And if I say no, he goes on to something else fairly quickly.
His "output" was really low today, I offered him lots of water but he didn't want much.)

What the heck am I doing?
Why did I say "boobies are for bedtime"?
Why am I still saying it?
