Atrial fibrillations the problem of irregular heartbeats, due to which clots can form inside the veins, and may lead to stroke, and ultimately, heart failure. An anticoagulant is given to such patients, to decrease the chances of occurrence of a heart attack due to blood clot formation.
Drugs are not a topic to be thinking about, I VERY MUCH WORRY YOU ARE ASKING NOT BECAUSE OF SCHOOL!!!
Give the baby something to do and watch her. Do no let her put sand in her mouth if she does and you don’t do anything then she will think that is ok. Therefore she will do it again. So I suggest watching her but giving her something to do.
Example: go get your feet went and take the baby girl with you to get her toes wet too.
Give her a toy to play with. Play with her.
Etc.
I hope this helps!
