Been thinking about this one.... OK.....Turns out Liz Foster is suffering from Dementia or something. She was confused about taking in a baby girl..Jill.....she actually gave away a baby girl....Lauren. Jill is actually a Foster but so is Lauren. Remember Jill's father walked out on Liz and the kids. What if Liz was pregnant and gave Lauren to Neil and Joanna Fenmore. Lauren and Joanna never really clicked so maybe this is why. What do you think?
