An insider told Star magazine:
“After several weeks of personal soul searching and talks and discussions with her mum Jamie Lynn reluctantly agreed that giving up the baby is the right thing to do. Lynne says Jamie doesn’t understand the life long consequences of having a baby. She still wants her daughter to be able to be a teenager, go to parties, hang out with friends and have a career. So she’ll take the front seat of caring for the baby and take the pressure off her daughter.” (Source)
