I've heard other moms say that they knew it was time to wean when their child lifted up their shirt at church and said something embarassing like "Booboo juice, Mom!"
I probably shouldn't wait 'til something quite that memorable happens, but as you know if you've read my previous posts, I'm just not a weaner . . .
My little Louella is over 2 years old now, and she's still nursing plenty. She'll ask to nurse by saying "I wanna nuhs" or "I wanna nuhs you."
The funny thing is what she says when she wants to switch sides, mid-feeding. She'll let go and say, "Udder side".
