Baby is 4 months old. Over the last few weeks, day naps have become shorter and shorter. Averaging 30-35 minutes which mean DD is ratty again within an hour because she’s not rested enough. They’re short no matter where she sleeps, although contact naps do last that bit longer as I can shush/pat/rock when she starts to stir. She ends up crashing and burning at 5ish which of course makes her 7pm(ish) bedtime difficult. Is this part of her regression? Do I just need to ride it out? Send help!! (And wine)
