Wake for feedings

Megan • Trying for our third! First baby a miscarriage, chemical then rainbow. Second baby 9 months of trying 4 with clomid. Hoping for a quick easy pregnancy for #3
At what point did you stop waking your lo for feedings? My LOis 5 weeks and gaining weight well. I stopped waking him at night it I usually wake him if he goes past 3 hours during the day. Do I still need to do this? How often does your lo eat in 24hrs and what age?
