dear god, you gave birth yesterday, you've had to cope with a move, big family changes.. and your family are all descending on you for a visit, in your home, and you're trying to establish BFing for the first time?
You need to take a step back and put yourself and your newborn first for a while.
You need to explain to your DH how you're feeling, get him on the same page. And STOP trying to pander to your family - why on earth are you worried about annoying them by having them overspill into your new home?
You need to get them to postpone the visit or make it on your terms (and that means you're not "hosting" them - they're there to see the new house, help you out in practical terms, then go away once you're tired or needing space to BF in a calm, private environment).
You are taking on too much, my love - please put yourself & your newborn first here, everyone else can and should expect to wait for you to recover, bond, and establish normality with your new expanded family.
Why isn't your DH protecting you here?
Why is your family being so insensitive?
I'm so angry on your behalf
