Not quite sure what the parents are calling the ceremony, but essentially it's a non-religious celebration of the baby.
Ordinarily for a baptism, I would get a sentimental type gift, the kind of thing you keep. Perhaps a nice book of children's stories, or a bunnykins bowl. I know, however, that the parents are feeling a bit strapped for cash and would find something practical like clothing really useful.
So what type of gift do you normally give for baptism/naming ceremonies? I know the parents are not expecting any gifts.
