Go half size up if you have a wide forefoot or are between sizes and otherwise true to size works. For jogging leave a thumbnail of room and a secure heel, try them at the end of the day to see if your toes hit, and expect no hot spots.

Congrats on your great grandbaby. For the newborn stage I vote for simple wins. Look for a small unit with a rechargeable battery, a basic on off switch and a physical volume knob. Choose steady white or fan noise rather than songs or birds since the constant sound is what masks household bumps. Put it across the room from the crib or bassinet and about an armspan or two away and and set the volume just high enough to cover footsteps and dishes. Not in the crib. If it runs all night, plug it in on a dresser so you are not babysitting the battery. Works great.
