First Sign???

I put PJ to bed a little early tonite. He didn’t have good naps and was tired. He went down with no more than 30 seconds of crying/whining for the third night in a row! He was asleep by about 6:45. He wokeup and played in his crib for a bit at 10:30. Josh went in and roused him the rest of the way. So I felt I had to go up and nurse him or else he’d have to cry back to sleep. I didn’t have the heart to make him do it again in one night. I went in and picked him up. I held him in the bed and spent a few minutes asking him what he wanted, cuddling and kissing him. He wasn’t crying, but definitely wanted something. Finally, he looked down at his hand and squeezed it. I really think he was trying to sign that he wanted to nurse! I did the nursing sign back to him and he chuckled. So we nursed. How could I refuse now!?
