DS is 4 months. He sleeps really well at night, so no complaints, but cannot sleep for longer than 45 minutes in a row during the day. This has been going on for at least the last 2 months. He blatantly needs longer naps, and I often end up resettling him if possible to get some more zzz. It also really limits my time to do stuff as once he's down the click is ticking...
Did anyone else find this? Did it resolve naturally? How long did it take?
