welcome.

well my now hubby had a child and gained sole custordy of him 5 years ago now, he is now 9.
he doesnt see or speak to his mother much maybe twice a eyar if he is lucky.

he was 7 when our first little girl came along, and he will be 9 when the next bundle arrives.

he loves being a big brother, even though he has 5 other brothers and another sister from his mum but once again never sees them.

the age was big and not planned by hubby, he was very similar to you decided one was enough as the age gap would be to much and so forth, then he met me and things changed lol..

so there is hope and it can turn out great.

dont give up just yet your still young and you have a great outlook on life and positive influence on your son.
