Question for mamas who have babies

Lindsay • After 9 miscarriages,we got our little miracle in Feb 2016. My little Aidan! Trying now for baby #2!
My little guy is now 6 months old. Everywhere I read says he should be napping for around 2-3 hours. My little man only does like 40 mins max! Anyone have a similar situation and how did you manage to get them to nap longer. I'm exhausted and can't get anything done around the house! Help 😩
