it sucks when this happens!
makon was the same slept from 3 weeks until 6 months and i think i could count on my hands the amount of times he has slept through since!!(yup he is 2.5 yrs old now!) he got teeth at 3 months so it wasnt them that caused the issue

im hoping Arquene will do the opposite!she has been a terrrible sleeper so im hoping soon she will start sleeping through!

i hope it all settles soon for you!
