Weird but cool

I was layingdown with my 1.5 year old and he was blowing bubbles on my belly.. he pulled my shirt over my belly and said "bye baby" and then cuddled with my belly. My hubby and I have been trying for baby 2 (had a mc in Dec) and I'm only 11dpo but after my baby fell asleep I took a test and have a super faint line!!! I'm only 3 weeks but how did he know?! Lol! I think.that is SO cool! Anyone else have some stories like this?!
