8/9 month sleep regression?

Michelle • costumer pianist. 2nd pregnancy!

Apparently it's a thing! This little guy was sleeping through the night like a champ, but has lately been waking up at 1 and 5, totally inconsolable on anything except being nursed. Ughgh. The 4 month had a similar experience, where for a week or two he added that 3-4am wakeup and then dropped it again out of the blue.

Anyway, if you have advice or just want to commiserate, fantastic! :)
