Anyone almost make it to 5 months without sleep regression until recently? DS will be 5 months in a week and a half and just recently has reverted back to 4 hours then every 2 hours at night vs the amazing 6-7 hours then 3-4 hours after that at the beginning of the month. He's already past the 4 month developmental leap and growth spurt so it seems a little off to have the sleep regression happening now.
