Gift ideas for husband on being a father

I plan to gift my husband with a t shirt saying "best dad" after my second child's arrival. I am not sure if he will be happy to wear it though coz he is a very shy a nd reserved kind of person.

If anyone here has gifted something unique to ur hubby after the baby's arrival then plz share. I dont want to give him any gadgets coz he's got all of it....i want to gift him with something that can be treasured.
Plz share ur ideas.
