Alva Baby and Newborn Disposables

🖤J.🖤
I am going to cloth diaper my little bug and am wondering if any mommas who use Alva baby think this plan will work or have some advice. I want to build up my stash throughout this pregnancy so it's not a huge bill expense at once. I think I want to use disposables when baby is a newborn because of the lovely tar poop. Many people really only complain that Alva is too big for their baby starting off because the legs are wider. For those who have used these, will newborn diapers typically get me to the point baby will be grown into Alvas? I'm not sure what disposable sizes to have ready. Also, did you find the diapers overall too bulky? I have heard so many good things about them that the sizing is my only hesitation. I also know every baby is different I'm just looking for some recommendations. Thanks!
