The social environment is helpful for child development - and with you being due in a couple of months, if she's exposed to other younger children, it might help her to accept the new baby into the family more quickly

i've read a couple of posts recently from you about being fatigued, so this might also be a chance for you to have a bit of "nessa" time - or to get things organised for the new baby.

it's never an easy decision - but i'm sure you'll make the one that is best for you and DD
