In the past I’ve gifted parents these: key ring with personalised photos; personalised photo cup coaster; hand drawn artwork from Etsy (give them a photo as reference); hand print photo frame. Could also get a babygrow/vest saying Happy Birthday Daddy and a personalised card. Not sure if they’re any good for you but hopefully they give you some ideas :)
Same for me too! I've been wracking my brain about it but still not thought of anything 😶 If I do I'll message ☺️
One of the things I got for my husband was a hoodie with our son's date of birth in Roman numerals, just so it wasn't obvious and he's not into big patterns etc. I also got him something related to The Office US, which we both love! A t-shirt saying Regional Manager with a baby grow for bub saying Assistant to the Regional Manager! He loved both. Also made mini chocolate tarts with chocolate letters on each one to say L O V E Y O U D A D D Y
I gave my husband a lego technics dodge charger for his first birthday as a dad and I gave him a iRobot vacuum for father's day (he does the vacuuming, so it helped give him a break)
My LG was born in October and my husbands birthday is in January. I got a photo book printed of photos of the 2 of them together and a card. Then sneakily used his 3d printer to print a sign for his home office door that says "daddy's office".
I’m in the same boat, thinking probably an engraved ring/jewellery with baby’s dob or name
