FTM here. My sweet baby boy is 4 months + 3 weeks and has been falling asleep independently since we gently sleep trained him around 3 months using “Give Baby A Chance.” He goes into the crib awake for bedtime and naps and typically sleeps 5–9 hour stretches at night with one feed (around 1–4am, breastfed). Recently, he’s also been taking longer naps (1–2 hours). He’s on a 3-nap schedule with wake windows of ~1.75/2/2–2.25/2.5 hours. First nap is usually 2 hours, followed by a 30-1h second nap, and final 30 min nap before bedtime.
For the past 2–3 days, his first stretch has shortened to ~2–4 hours, followed by wake-ups every 1.5–2.5 hours. He fusses/cries for 5–10 minutes, then falls back asleep on his own—no intervention needed (last night this happened 5 times).
Could this be the 4-month sleep regression even though he’s already sleep trained? Has anyone experienced something similar?
He’s had occasional off nights before (usually followed by a new skill), but never for this many days. He also wasn’t a great sleeper as a newborn, so I’m unsure if he’s already gone through the regression.
Thanks in advance!
