Toddler sensing pregnancy?

Does my toddler know something that I don’t?im driving myself crazy here. I’ve taken two pt, both BFN. Cycle is 1 day away. I’d say I’m in tune with my body however.

Nonetheless, my 15 month has been behaving differently. She has been rubbing my nipples between her fingertips. She has even tried to latch on. Totally had a melt down when I said “Ouch! No) She hasn’t been breastfed in 12 mos give it take.

She has been doing all the typical old wives tales:

Standing on her head

Looking between her legs

Looking under my dresses

Crawling between my legs

Patting and kissing my stomach etc

Anyone else experienced this????

I’ve also have been seeing and hearing signs the last few weeks.
