Don't buy loads of stuff until you work out what you need (amazon prime is helpful here)
My DD is 3 months old and so far...
I didn't need that many maternity pads, I used about 1.5-2 packs of boots ones and switched to normal heavy pads asap
I have used about 5 boxed of breast pads though and hate the wet feeling of reusable ones
My baby will not keep a hat on, bonnet that ties on solves that issue no DP she doesn't look like a monk
Baby hates lying in the big bath or sink, schnuggle bath where she's sat up stopped the crying
She will burst or wriggle out of a wrapped swaddle so the zipped one is better but a pain so only used in desperation
Certain music may help calm her down but it drive you crazy after a while, same with while noise (luckily she goes to sleep quickly with that and it can be turned off)
Baby won't take avent bottles anymore after a break from them (breastfed), mam bottles work so bought one of those, only have 4/5 avent bottles so it's not huge waste but hopefully she'll get used to them again
Didn't introduce dummy because I didn't want to maybe affect breastfeeding, we have one that is used to help with bottle feeding but up until very recently wouldn't suck on one anyway so am trying to get away with out having one.
Sainsbury's nappies suck, Morrisons were meh, Lidl's are good. Not been to Aldi yet and forgot to try the pampers we got for free so they are sitting unused waiting to be donated.
We got wrap over bodysuits and have since bought bigger sizes because they are soooo much easier to put on a tiny baby
I can't really sleep during the day but the fatigue fog lifted after the first week
I have a cheap wrap carrier that has been a god send at times when she wanted to be held and held and held or she would cry and cry and cry.
Baby sleeps in bed with me and we all sleep better, 40mins vs 2-3 hours at one point, she started doing longer day sleeps without me and then has only just started sleeping in her cot at night.
I have a pretty much permanently stocked nappy bag so I can pick it up and go whenever
I go out a lot, and have done since she was tiny, surprises a lot of people but it helped me feel more normal-ish. Try to have a couple regular things so there is so semblance of routine not days passing in a blur.
