How do you get your baby to nap in his crib during the day ?

It’s become almost impossible to make my baby (11.5 weeks) to nap in the house and in his bed... I try putting him in his bed when he’s drowsy and tired but as soon as I put him down he wakes up smiling and moving or crying ... The only way he will nap is if we go out with the stroller or in the car, or in my arms after a feeding 😭😭 Do you have any suggestions ?? At night he falls asleep after breastfeeding (in my arms) and I put him in his bed without problem and will sleep for a 6-7h stretch.
