I didn't sleep train at 2 months, But I know when my daughter was two months old, I used a white noise machine, humidifier, pacifier. And a tight arms free swaddle.

@kreeblim, what did you do for sleep training?? I'm having trouble with my almost two mth old to sleep longer than an hr and a half at night at a time

I used sleep training and got my 8m old sleeping through the night and she learned to self soother. Before then. She was up for a bottle 3 times a night and would be up for a couple of hours. Her demeanor is brighter and she's an even happier baby.
