Oh yes, you will cry and cry. I think it's just a way of getting rid of excess water or something!
Get a lovely box of tissues, or a muslin!
Book yourself a massage for those aching shoulders, and do some weight lifting now for your upper arms to strengthen them. I also had a baby who was happier in my arms, and I can remember the pain...... I got a lovely sling in the end and wore my babe all day every day- even went to the loo with her strapped to me.
Be prepared for massive arguments also with your partner- sleep deprivation is a torture method for a reason.... Don't try and out do each other with I'm more tired than you antics... Life's too short, just be kind to each other.
Yes yes to filling up the freezer, and yes yes to taxing all visitors with dinners and cups of tea.
If you can, get a dishwasher if you don't have one, and a tumble dryer is very useful too.
Even if you plan on breast feeding, get a few bottles and a steriliser... you never know if you'll need a bottle of formula now and then.
Most of all, slow down and cuddle your babe, and recover from the birth.
