Sleep training

Ok ladies, anyone who has done sleep training (any version of letting them cry) WhT do you do at night? Do you go in when they wake up immediately and reassure them you’re there still? Do you just let them cry? How long do you let them cry for before going in? What’s the max amount you let them cry before caving and picking them up.

I don’t want anyone’s judgment on “don’t do cry it out”. Trust me I don’t want to do it. But I do want to have my baby learn to self soothe a little bit.

Thanks in advance
