is 0-3 month different then just 3 month size ?

It's about the same. 3 months is normally 0 to 3. Newborn is the same as up to 7, 6 months is about the same as 3 to 6. It gets confusing lol

peopke say 3 month will last up to almost 6 months .

0-3 months has to be smaller then 3 month

0-3 months is a little smaller than just 3 months

yeah i figured thanks girl i figured after newborn she will go right into 0-3 month and after that 3 month will last a littke bit right

It is smaller
