I don’t think anyone else posted this, if they did I apologize.
Please realize that OTD is not a line in the sand, saying Abandon all hope, ye who enter here . The schar of doing a single Mitzva is impossible for us to fathom, and you should encourage your children in all ways possible to do even a single mitzva if they are not at the level of doing all of them. For example, if your daughter is by you and you convince her to join you in shul on Rosh Hashana, she will hear shofar! What a Zechus! Even if she just lives with you in your home and does nothing else , she is mekayem the mitzva of Ner Chanuka when you light them!
Besides (even without the Jewish angle), what is her other option? Living in the street? With a “friend”? As a mother, do you want that for your daughter?
Of course not.
