Nap trapped

Chase

Anyone have any tips for getting their baby to nap in their own bed? I do still love contact naps with my boy but it’s getting harder to get him down and there’s lot of stuff I need to do. He used to be able to take 1-2 naps in his own bed but after this 4 month regression anytime I set him down he will cry forever even if I go in to reassure him and then leave. Nursing/rocking doesn’t work either 🥲
