Hi Velvetee:
Your question has been answered by others but you might like to know the significance of jointly registering the birth of your child with your partner. Doing so will automatically give him 'parental responsibility'. (Otherwise he could only obtain it through entering into a formal agreement with you, or by obtaining a court order):

I hope that things are going well for you, and that you will welcome your partner's formal involvement in your child's future, but you ought to be aware that, if you separated from your partner, he would still have a say on whether, for example, you could take your child out of the country.
I hope that you don't think that I'm trying to tell you how to run your life. I'm simply seeking to point out that whether or not you jointly register the birth is a major decision, which could have important consequences in the future.
