Congrats - The most important thing is your love and time !!!!!!
Sort out a 'offical' arrangement through csa which is child support agency and give regular money every week or month through them, this way she can never go to court and say you havent paid anything
Ask her what the baby needs and what size clothes the child is in, babies grow fast, then if u wanted to you could send gifts in the post or take gifts with u every time u go there, but remember gifts are not important.. The mother might prefer that you buy 5 tins of baby powder , nappies, high factor suncream for example and this would benefit more (especially if they havent got much money)
I think u need to make sure ur name is down on the babies birth certificate
And make a plan for regular contact
Musical toys, rattles, soft toys, bath toys, soft books are best for a young baby..
As i said... All that baby needs is 'you' , your love attention and your time..
Good luck and congrats
