Sleep Training Twins

Porsha • 27 year old first time mommy to twin boys Ethan & Elijah born Feb 28,2019

We started sleep training a week ago and everything worked out well we were down to only one feeding at around 3-5 in the morning BUT we had babies in separate rooms now that we placed them in the same room they are waking up 2-3 times again but they are both also teething...any suggestions
