How tall was your LO when they no longer fit in the PNP (the bottom, not the basinette)?
I was looking at DD in it the other day, and we have a while to go, but if she keeps growing at this rate, she'll no longer fit in it to sleep by the time she's a year old!
Re: When does LO no longer fit in the PNP to sleep?
I don't have the answer for you, but it seems like the others provided you with good information. I did want to mention that their growth does slow down. DS was growing 2.25 inches/month in the beginning, but only grew 1" between 4 and 6 months and another 2" between 6 and 9 months.
