We are enjoying being parents, it's tough at times but getting there - he slept for 6 hours last night which was his personal best.
Lots of people will be wanting to give you advice, including me right now, but take it with a pinch of salt - you will find your own way - what's right for you and the twins. So fuck 'em (the adults).
You'll see this advice elsewhere but whatever you do, don't have parents/grandparents/friends around as soon as they are born or in the first few days, you need space to try and get used the new normal and working out what you are doing - people want to think they are helping but they don't. Set their expectations that YOU will invite THEM over when you are ready (not the other way around). Set the amount of time they will stay with you, e.g. 2 hour visit, and don't have anyone staying in the same house overnight. I made my mother in law cry by telling her she can't stay with us for 1 week every month (seriously) but it's not about your parents, it's about your sanity and being able to look after the babies and when you're sleep deprived; you don't need people flapping around you you're doing it wrong or telling you how they used to do it (because advice changes for a reason). They think they are helping but they aren't. We finally had a good parental visit just last weekend, they were actually useful and did not get in the way.
Baby stuff is expensive, much of it you can get second hand off Gumtree etc - the only stuff you should buy new for sure is the base for the car seat, if you buy second hand you don't know if it's been in an accident. They don't care what they are wearing and they will just puke and shit on it. All they want is food, warmth and somewhere to sleep. Toys are pointless until at least past where we are (10 weeks), people will buy you shit but don't encourage them - if they ask what you want, you want nappies, baby wipes.
Friends with kids will probably pass on clothes (we have bought not one thread of clothing). I am seeing friends this Friday, we are passing on actually useful things like nappies, cotton wool etc.
Batch cook food - in the run up we cooked loads of stuff and froze it meaning you don't rely on take away, chocolate or nothing. It's great having decent food and not having to spend time cooking that stuff.
The single best thing we did... NCT classes, they were worth every penny and more, they helped...
1) Set our expectations of what life will be like as new parents
2) Educate us about what birth will be like, preferences, painkillers, and how to look after a newborn
3) Meet people in the same boat - we moved here a couple of years ago and don't have many connections locally, let alone people with kids. Not now though... Amanda is out nearly every day doing something with other mums, even if it's going for a walk in the park. We have a WhatsApp group which is great for whinging about stuff or asking things like, are you guys having this problem etc. etc. It's just moral support from people going through the same shit (literally).
Congrats again mate.
