Leaving Ava unattended.Lynn uses the incident as an opportunity to shame Haille for being a terrible/neglectful mother. The confrontation is nasty, and Megan takes Haille and Ava home. The stress of everything is not good for Haille's sleep, and she is becoming more anxious by the day. She starts missing days of her medication and losing her baby everywhere she goes.The back door is left ajar at night, and Haille finds some vandalized paintings.

They agree to take Hailee on, but she needs to update her portfolio, which means no sleep for Hailee. She starts seeing someone following her and grows increasingly paranoid about Lynn.Hailee is locked in the garage and frantic when the baby starts crying. She is convinced that someone is trying to steal her baby. It is James back early from his work trip, and he is seriously concerned.

It was a calculated attempt to get Haille committed. (thanks to lifetimeuncorked)
