my little boy has always been a good sleeper since we brought him home and once he was over birth weight and we didn’t need to wake him he would do 6 hour stretches at night! he’s even done a 9 hour stretch before so never really struggled with day and night confusion. he’s still aware it’s nighttime at the moment as he goes straight back to sleep once i pick him up but he’s waking every 1.5-2 hours all of a sudden the last like week and i’m just not sure what the reason is as nothing else has changed and he doesn’t want feeding he just wakes and needs resettling! i don’t mind resettling him obviously i just wasn’t sure if this was the 4 month sleep regression? i know it can come between 3-5 months and he’s almost 3 months in just over a week and he was 2 weeks late so adjusted age would make him over 3 months so is that what this is??
