I enjoyed having newborns, even from my first. For the first 2 weeks with the first I did feel like I’d been in car crash, physically and emotionally.. but somehow I still really enjoyed the baby around that too!
I have fond memories of reading the Harry Potter books while DS lay on my chest and slept.
I found the “sleep when the baby sleeps and abandon the housework” bit particularly easy though, as I was never particularly house proud to start with 😁
Also, only breastfed for 2 weeks with each baby, which made a big difference to me. That was only because I really struggled with it each time though (despite visits from health visitor, going to peer support breastfeeding groups etc). A lot of people seem to find breastfeeding much easier than making bottles, and it looks that way when watching women and babies who have the knack of it. If that isn’t you though, don’t beat yourself up about it (and the ready made cartons are a godsend).
I also used a dummy for sleep, with all my DC. Again, views on that are mixed, but I think that is probably another factor that made me experiences feel relatively easy, at least some of the time.
We had a little morning routine - same time each day - when I had breakfast, fed baby, had a shower (brought baby into bathroom in bouncy chair), then bathed and dressed baby, with some nappy off -on the mat - time as part of that.
After that, we’d have gone back to bed if wanted, happily spending the day watching tv/reading/feeding - or gone out for a walk, shopping etc. When you don’t have older DC, you can really take the pressure of having to make dinner at a set time etc
I’ve got 4 DC and they are obviously all different. Two had awful colic, one took years to sleep through.. but the main routine was always the same in the early days.
Also, if you ever do have to deal with a newborn who keeps crying and you can’t seem to solve it, it is okay to put them in their cot for a few minutes and shut the door while you grab a cup of tea and a breather. A health visitor told me that once and I think it is good advice. Obviously you don’t want to abandon a crying baby on a regular basis, but 5 mins when really necessary , to save your sanity and regain patience, won’t bring them to any harm.
My other tip is : Don’t wait until a baby is obviously really tired to encourage a nap. If they have been awake for a while, or are showing signs you recognise as tiredness, then you swaddle them up and pop them down in a basket or baby chair - still within your sight - (and this is the point where I’d give a dummy) and then they can watch you and feel safe while they doze off (then you get a tea break). If they become overtired and overstimulated then it can be a lot harder to settle them down, so you can always keep an eye on it and give them the cues to settle.
