My dd is 7 months but I spent yesterday with my friend and her 2 week old dd and it reminded me of the early days.
Most babies just want to sleep and eat in the early days - especially on someone.
Remember they've spent 9 months in a nice warm, snug, womb being with you 24/7 so that's what they really want once they're out in the world. I think it helps to understand this as you can then Understand why they might not be too happy about going into the mosis basket etc.
If you are planning to breast feed I found it helpful attending the weekly breast feeding drop ins for support but also somewhere to meet people, chat, get out of the house and start bf in public. Might be an idea to find out where they are now.
My dd would feed for ages in the early days so get comfy on the sofa/nursing chair. Make sure you have a drink within arms reach (in a bottle on sofa), snacks, phone, tv control etc.
Now she only feeds for 10 mins max and I miss those early feeds where you could relax and watch tv!
Try and get out everyday. Good for you and baby.
If dd fell asleep in the car or pram on the way home I would bring her into the house but leave her in the car seat/pram and have a nap.
You are a lot more able to handle the nights if you can get a break during the day/evening so if family or friend can take baby for a walk or just cuddls whilst you get an hours sleep is also helpful.
Basically enjoy the cuddles on the sofa it doesn't last for ever.
