That is wonderful you have such friends who feel you are a great mother, ekblad+ and the fact you haven't left your children except for overnight is great and obviously your choice entirely. Never said it wasn't.
But ITA with the
smilie you included in your OP when you stated the number of days you would be absent.
I don't think anyone here is wishing sorrow upon you or your nursling. To act like this isn't a big deal, that there isn't a wealth of data supporting gentle, easily retractable decisons when it comes to nursing such a young baby is to be foolish about this.
Definitely put up the photos, call your children, make it fun. Pump for comfort. But let's be real here: There isn't the possibility of comforting your child upon a complete cessation of nursing for six days and that is a big deal. Why else post a smilie like this?
I know it is popular to say 'oh, don't worry, the child will be fine' but people like Dr. Sears, kellymom.com, Joseph Chilton Pierce, and other AP folks have spent many, many years trying to get it through the Western World's heads that kids are not 'fine' when we rush them toward milestones they are not ready for, or remove essential nutrition and comfort like nursing abruptly. Not saying that is your son.
No one knows for certain how your child or other children will react. I do not understand what mcimom meant when she said she wished your 20 month old could be with your parents and other siblings. Does this mean he is not going to be with his brothers and sisters during this time? That might be more than enough disruption for such a wee one.
I hope you have a great time and are able to heal. I never wished you any harm. It is fair to acknowledge that the six days your son will have without you could be difficult for him. Maybe all the photos and phonecalls and treats will make all the difference in the world. I hope so.
