I cant remember how target up n up brand diapers are made… Would you use a box of those or pampers first? Not worried if my kiddo would outgrow them as i have another one coming. Would just like to ude the brand that is made smaller first
Honestly every baby is different. My daughter could only use huggies snugglers without breaking out or giving her a rash. 
Up n up was our brand of choice for my son. He would leak through pampers, huggies, etc. Never had an issue with up n up though. And hey, you can’t go wrong with them being cheaper.
My daughter would use rascal and friends but the Walmart parents choice the baby was allergic to
My honest advice as a infant teacher is to buy a small pack of several brands and try them out before you sink money on big box’s. I’ve seen waaaay to many parents sink money into box’s of Millie moon and honest and the kids allergic or they don’t fit well
