Growing up

I am pregnant with my second child, just found out a few days ago. My first child is 2, I am a stay at home mom and she is the light of my life. It could be because the news is still so fresh but I keep giving her extra cuddles because I feel like she’s not going to be my little baby anymore and it might be the pregnancy hormones but it makes me want to cry. I don’t know what to do! Lol. I feel like I sound ridiculous but I’m so serious! Anyone else ever have this when they got pregnant with their second?
