I suggest that you choose online classes according to your own needs. If time is tight and conditions permit, it is still recommended to sign up for a class and learn from the teacher.

Give you two suggestions:

? Check the school license to see if it is formal? Check the teacher's situation and see if the teaching quality is good. The advantage of doing this is that you can really learn knowledge and skills with less money.

Beside the Sanyuanfang subway station and Sanyuan Hotel in Suzhou, there is a training institution for baby nurses, which can take exams and obtain formal certificates. I suggest you have a look. What's its name? I can't remember the specific name.
