Parents who co-slept, contact napped, fed to sleep etc. - How is it going for you now?

Our LO is 3 1/2 months old and has and always had a hard time sleeping. We’ve tried all the different strategies and tricks out there without much success, so now we’re just going with what gives us at least a few 30 min naps a day and some sleep at night. This includes co-sleeping (safe sleep 7 and we live in a European country where it is not frowned upon so no hate for it please), contact napping and feeding to sleep at night.

Parents who have done these things as well and whose LOs are a bit older - how did these things work out for you and how is it going a couple months down the line? Did you eventually sleep train or did your kids sleep needs and habits just change with time?
