Accepted Answer

Hi Dragana,
yes, there is a problem with being able to post full questions. A lot of people suffer from it. I did bring it to the attention of the kwiziq team. If you want, why not send them a mail (under Tools > Help & Support).
Yes, "je m'endorme" is subjunctive; "je m'endors" would be indicative.
About your second question: you could also say "les bras" but in this case "ses bras" just stresses the fact that they belong to the mother since there is more than one person involved.
