Eevee Where Are You???

I’ve been all over Route 4 looking for Eevee. My son caught it literally as soon as he got there. I cannot find one ANYWHERE. I’ve tried the Bridge Area in the Wilds. I’ve been on Route 4 for ages. Is there a specific grass patch or something I’m missing?

Edit: For the record, this wasn’t a huge deal at first. But I have a 6 year old checking in with me on a daily saying “Did you get an Eevee yet? Oh… that’s ok. I’m sure you’re trying your best.”

Update: Thank you to those of you who recommended Pokemon Home. I now have a nice and shiny Eevee to show off to the small child.
