DS1 was a pretty good sleeper and was definitely STTN by 12 weeks but DS2 seems to be stuck at 3.5 hour increments at night. He fluctuates and has done a handful of 5 hour chunks and one amazing 6 hour night. But with a toddler and a baby, my hubby and I are soooo sleep deprived and exhausted all the time.
ETA: sstn = five hour chunks or more each night consistently
Since we're nearing the 4 month regression I'm wondering when we'll hit longer sleep intervals! We also can't load him up on milk before we put him down because he spits up so freaking much.
If your baby wasn't STTN by 4 months, was the regression still as tough? how was your LO's sleep at 12 weeks old?
