She said she realised from comments on here /sent to her that the babies were in walkers too long. Her reasoning was she finds it hard to look after both when Donna isn't physically able to chase after them etc so it was easier to have them in there. She was kinda nice about it, saying she isn't perfect (who is!) and is glad she made the choice to give them more floor time as they are now happier.
*However* during this Snoop Don was butting in with "well theres nothing wrong with walkers" "they werent in them 24/7" "you're only young" etc
