No visitors for at least ten days - entirely up to them, plenty of people talk about 'pulling up the drawer-bridge' post birth.
No advice to be given by visitors or sharing their experiences - advice, unless asked for, is not advice, it's a lecture. People have a weird compulsion with pregnant women and then newborns, they like to tell them their horror stories of terrible labours and stitches and no sleep and reflux and not having any time to think for the first 7 years. Wildly unhelpful.
Only stay an hour - not unreasonable, it's knackering being the mum of a newborn.
Visits to be arranged in advance to fit around breastfeeding - establishing and learning to feed is often very hard, quite painful and tricky, not wanting to do that with an audience is again, not unreasonable.
There’s an Amazon gift list, if we wish - very organised, no wasted money and no 94 baby outfits in the same size they'll never wear.
Wash your hands - you should do this anyway.
Get changed if vaping or smoking - you should also do this anyway.
You probably won’t get to hold baby - nobody visits a newborn with the solid expectation of whipping it out of the mum's arms, if you do, have you thought of maybe a puppy?
Don’t kiss baby - this 100% shouldn't be happening.
Give baby back immediately to mum if crying - general common sense.
Presumably you have an issue because it contradicts your expectations of how you wanted the visit to go. It's not about you, it's about them.
Similarly, the best visits I had were from people who showed up, made sure I had a full bottle of water, a cup of tea, a snack, was comfy, then they put a lasagne they'd made in the fridge for later, hoovered the stairs and put a wash on and then left. Absolutely brilliant and continues to be the best most supportive friend I have.
