Oh this is lovely, huge congrats
We have a 19 month age gap so semi similar, it’s chaotic at first but now they’re absolutely inseparable and I know it’s cliche but watching their bond grow is just the best and most heart warming thing ever. I was actually just thinking to myself this morning how brilliant it is that we were able to give my eldest a sibling with a smaller age gap because it teaches them so much that you don’t even realise.
My biggest tips are go easy on yourself and your expectations of your household, not everything can and needs to be cleaned every minute of every day and if it needs to be left then leave it so you can rest while you get a second and also not everything will go to plan - accept, take a deep breath and try again later, you do find you roll with the punches a lot more. Get a really decent double buggy that can go literally everywhere on all terrains to take the anxiety out of taking 2 out of the house (the out and about v4 double has been my absolute godsend) oh and….always do your big shop online for delivery
