[2shoes]

they will have been together about 3 months,
do I.........
a) send her a card via ds post
b) get dd(sn and adores her) to send a card.
c) buy her a pressie(small)
d) just say happy birthday.

???????????????????

Definately a card - this could be your future DIL you're talking about . Present not necessary but if you decided to, something like an iTunes voucher is well received by most teenagers.

she hasn't got a home pc.

card from you and DD.

Definitely a card and just a small token gift - some toiletries/box of celebrations??

Or call credit. And I hope she treats him very kindly!

oh she does. thay are so sweet together
