LO sleeps 12h a night with one short wake at the 9h mark.
I love the fact that I get nighttime sleep and usually wouldn't push for a nap other than LO gets super cranky without one. He is 14w old.
His first nap is 45m
2nd nap 45m
And 3rd nap (by now he's super cranky) is 1.5h
All are about 2.5h apart

Should I try to extend the first nap? What will likely happen to the other naps if I do so?
Any advice or experience is appreciated!
