It is happening, and has been for a long time. When my first daughter was a baby, so around 2015, my wife and I were discussing options for helping her prop herself up, and came up with the idea (on our own, as far as I know) that a horseshoe shaped pillow would be perfect. I picked up my phone, opened the Amazon app, and typed the letter "h". The app autocompleted "horseshoe shaped pillow" based on just the one letter.

These are common baby items. If you searched for baby stuff on Amazon or anyone in your household sharing your IP did, and especially if you purchased baby stuff on Amazon, they're going to recommend baby stuff more often. It's called an a priori algorithm. It looks at what other people purchased that have purchased similar things as your search/purchase history and recommends based on that.
