Did your LO resume their normal sleep habits once the growth spurt was over? DD has been STTN since about 2 or 3 weeks, but this past week she has woken during the night a few times and has a hard time getting back to sleep. Last Sunday she hit 12 weeks, so I'm assuming she is going through the 12wk growth spurt. So, did your LO have a sleep disruption during their growth spurt, then go back to normal when it was over? Also, how long did it last? TIA.
