Im not going to do it... No matter what.
I dont feel it is safe, and anyone who I actually know IRL who has co-slept is having the worst time re-training their toddler to sleep alone, it is a nightmare for them, and IMO not something the child has to go through.
Personally I believe in having a good routine, and that means starting when they are babies and still very adaptable.
Having a baby is a definate test of will, mothers only want their babies to be happy, but sometimes that also means making hard choices, one being letting them self-sooth sometimes, even though it hurts us to hear them cry... and for me, the other being getting my baby to sleep alone, which may very well be hard in the beginning.
However, everyone has their own beliefs and experiences
