AITA for not letting my daughter around his gf?

A 32-year-old new mom welcomed her baby girl in August, only to face drama from the 42-year-old father’s new girlfriend—who called her one night cursing both her and the newborn until paternity was proven.

The couple split early in the pregnancy over his infidelity, and soon after, he moved in with this new woman. Her aggressive phone call led the mom to block direct contact and insist the girlfriend stay away from the baby, especially since the dad still hasn’t completed his part of the paid-for DNA test despite plenty of chances to be involved.

‘AITA for not letting my daughter around his gf?’

The drama unfolded right after the birth, with the father showing little interest from the start:

In an update, she shared more about her concerns and legal steps:

The girlfriend’s outburst—calling to curse out a new mom and her infant—is a massive red flag that screams hostility. Any reasonable parent would keep their newborn far away from someone acting that aggressively, and the dad’s failure to shut it down raises serious questions about his judgment.

Right now, since they’re unmarried and he’s not on the birth certificate, the mom holds full legal rights in her state. This gives her complete control over who sees the baby, making her boundary perfectly valid while paternity remains unestablished.

Family law experts consistently stress that an infant’s safety, both physical and emotional, comes first. Introducing a volatile stranger isn’t worth the risk, especially when the dad has skipped the birth, declined prenatal testing, and still hasn’t completed his side of the paid DNA kit.

Bottom line: get everything formalized through court—force the paternity test, secure child support, and establish custody. Document those threatening messages as evidence in case restrictions on the girlfriend are needed down the line.

Here’s what Redditors had to say:

Most online users side firmly with the mom, urging her to protect her baby and go legal fast:

All things considered, the mom is absolutely justified in shielding her newborn from someone who’s already shown outright hostility, especially while the dad hasn’t stepped up legally or emotionally.

That said, many point out this control is temporary—getting court orders in place soon will protect the baby’s interests long-term. What would you do in her shoes—hold the line forever on the girlfriend, or ease up once everything’s official? Would you even let the dad visit solo right now? Sound off below!
