Congrats on ur new baby and welcome to this forum, i hope u will enjoy ur stay as we all do ...
i think each puppy is different with potty training and sleeping through the night, but i would say a few weeks ... i guess i really am very lucky with mine, since the first night she never let a peep... i keep her potty right there with her during the night incase she needs it, i use a real baby campingbed that has netting on the sides and is big enough for her to sleep on one side and the pee pad on the other end and theres no way she can get out and wonder off during the night
hoeray to campingbeds
