Sleep training

I am aware some people are against sleep training. However, if you plan to sleep train in any method (there’s several different ways to do it )...

I likely will have to do it on my own. I do the “night” wakings etc in our house . I imagine the training will fall on me also. I’m pretty nervous I won’t be strong enough to even make it through one minute of crying. We will likely do Ferber or taking Cara babies.

If you did sleep training without the help of your partner at night, how did you do it? Any tips from those of you who have done it or those that plan to?
