Getting baby to nap

My son is 8 weeks old and will only nap while being held during the day. If I get him to sleep and put him down he wakes up within 20 minutes and I have to start all over. We’ve tried putting him down drowsy but awake and that never works.

Any other mommas have any tips/advice? He’ll sleep in the carrier but I go back to work in a few weeks and don’t want this to be an issue. I love the baby cuddles but need to be able to put him down occasionally for my own sanity!
