feeling the baby

Is this like normal? This is my first. At 16 weeks I was feeling the baby like little pops and from what I've read and asked that's what it feels like at that point. I'm 18 weeks now and even last week I put my hand on my stomach and actually felt the baby! A few days later I was able to feel it again a little bit. But last night and this morning this baby is just going crazy! He/she is just moving everywhere and I can feel it again having my hand on my stomach. Am I just being crazy or is it really the baby like I'm saying it is?
