Baby is 16 weeks now. At 15 weeks he started having some days where he will only nap on me, and will cry as soon as you put him down in his crib (not typical for him). On days he will nap in his crib, it will usually only be for 20-40 minutes. Still sleeping a good length at night before getting up to eat, but either won't go back to sleep afterwards (up for the day earlier), or a lot harder to get back to sleep.
