Reddit reviews I Love you Daddy (Picture Board Books)

There are a ton! I got them from Amazon. Once I looked at one, I just followed the recommended titles and found more lol. These are the ones I got:

Just me and my dad: https://www.amazon.com/gp/product/0307118398

My dad loves me: https://www.amazon.com/gp/product/1934082848

I love you daddy: https://www.amazon.com/gp/product/1445462893

Because I'm your dad: https://www.amazon.com/gp/product/1484726618

"Just me and my dad" is his favorite. "Because I'm your dad" is a good one but at the end it says "I do all these things because that's what my dad did for me," so I'd only recommend it if your husband has a good relationship with his dad. My husband's dad passed away a decade ago, so I think it's a little bittersweet for him.

Edit: Not daughter specific, but I think all are gender neutral.
