Sorry Im almost 19weeks & have the pack n play &stroller combo
By 16 weeks I had a crib, swing, bouncer, clothes, bottles, pacifiers, blankets, socks, shoes, mittens etc. The basics. I was 24 weeks when I bought a stroller and carseat. I'm 29+5 and have everything purchased already.
Oh and almost forgot I have a pack n play too
Ftm -7 months tom. So far i have a stroller car seat bouncer swing pack and play play mat.. shower gels lotion ointments.. little outfits socks detetgents sanitizers grooming kit bibs wash clothes towels baby bag and such. When i find a good bargain my bf and i take advantage.
There's no right or wrong answer but I'll tell you what I have and I'm six months btw. A couple packs of diapers and wipes, some onesies, a stroller,a carseat, and a baby bath. I just buy here and there when I can. I try to shop for the best deals being that I'm on a tight budget already. Me and my bf are in the process of moving soon. So I would say the most important things are carseat,diapers and wipes. Congrats :) Good luck.
Im a ftm but I have newborn to 3-6 months clothes, some bibs, burp rags,& started wipes & diapers (I buy a pack every other week in different sizes)
