Jack has his first tooth popping up! I was feeling around in his mouth, like any nosy mom would do...and I felt something sharp. Sure enough, one of his front, bottom teeth is coming in. This explains the lack of sleep last night.
I was proactive tonight and put him to bed with some baby Tylenol.
I won't lie...I teared up when I found it. My baby is growing up too fast. I'm afraid I'll blink and he'll be in braces. Braces are expensive!
