Yeah it is; the kid needs a father.
Bristol has a family/network to help her and the kid out.
If Johnston’s doper mother is an indication of his side of the equation, they’re both better of without him.
The kid still has a father.
Even if they meet and marry other people, the baby still has two parents who hopefully will be mature enough to maintain a respectful relationship with each other and a loving and involved one with their offspring.
