The baptism could be several years after the date of birth, so it could be a long search!
Sometimes several children from the same family were done in a batch, so it might be worth looking around the time of brothers or sisters. I had an instance where four children from the same family were baptised on the same day - oldest in their teens, youngest about two!
If you know the dates of birth for siblings would be worth adding them here as well.
The other thing that sometimes prompted baptism was an impending marriage - either of a mother/father to another partner or of the person themselves.
