I’m 23 weeks pregnant with a little boy. 💙

I’m 23 weeks pregnant with a little boy. Sometimes I feel this weird filling up feeling in my stomach and when I touch my stomach I have rock hard bump on one side like his head or bum is pushed right up there! I get this daily which I love but anyone have any idea what he’s doing or what the rock solid lump is? After about 15 seconds it settle back down to being squishy again haha!
