Divaskychick- I am 4wks into being a first time parent and things that would have helped me I think:
Have no expectations of yourself or at least lower them to rock bottom! If you aren't dressed at noon for the sixth day running it doesn't matter. Housework certainly doesn't matter.
You do not have to pretend to anybody. Don't say 'it's fine' if it isn't.
If you can't face visitors please just say no to them or better still get a dh/dp to do it.
Ask for help as often as necessary.
You will feel guilty, maybe a little, maybe a lot. Whether it is leaving the baby to cry because you have to have two minutes alone, not loving the baby straight away or using formula for example, it is normal to be wracked with guilt.
Physically it is quite shocking. The exhaustion, the lochia, the anaemia etc all have such a debilitating effect.
The baby blues are more than feeling a bit blue in many cases. If on day 3 you hit a hormonal, weeping, confused wall you are entirely normal.
Sleep at every available opportunity. Honestly, you don't need to do the laundry right now, you need to sleep.
Breastfeeding is difficult, painful, tiring, confusing, worrying, constant and a skill you have to learn. Get the help with it early on.
I know that all sounds fairly negative. Needless to say I absolutely adore my dd, she is the greatest thing that has ever come into our lives and every moment is worth it. Even at 3am on day 3 when I sat in bed, nipples bleeding, lochia soaking through the mattress, baby screaming, me sobbing, the cat weeing on the carpet, utterly exhausted, cs scar throbbing, desperate for the loo and frightened out of my life, it's still worth it. And even 4wks in it gets easier every day.
