Jeremy Renner's Estranged Wife ... I Didn't Choose an Uber Over Our Kid

Jeremy Renner's estranged wife has fired off a response to allegations she's a horrible, neglectful mom who extorted her husband ... well, she responded to everything but the extortion thing.

Sonni Pacheco says Jeremy is lying in his legal docs when he claims she hopped in an Uber and left their nearly 2-year-old daughter Ava alone for 15 minutes. She also says allegations that she was smoking and drinking during her pregnancy are a lie as well.

She says she did NOT stop breastfeeding because she was hitting the bottle. Sonni says she stopped because her diet was making Ava gassy.

She also says she's a doting mom and Jeremy is spotty when it comes to caring for the kid. She mentions an incident shortly after Ava was born, claiming Ava burnt her head on his fireplace glass and he expressed no concern other than to tell her to bring over some polysporin.

Here's what she doesn't mention ... Jeremy's business partner said in his documents Sonni allegedly tried extorting Jeremy, saying she'd release embarrassing videos of the actor if he stopped helping her get a green card. She makes no mention of this in her legal response.
