June 4th baby

My son will be 12 weeks old on Tuesday and has been sleeping a lot today and last night. He did have a more eventful past couple days, but I didn't think it would make him sleep this much. Last night he had a bottle at 8:30 and fell asleep about 10:30 and I woke up at 5:26 worried, made a bottle and he still didn't seem starving. Then he's just slept a lot today between feedings, already slept 12 & a half hours according to what's logged. Any other little ones around this age sleep this much? 🙂
