I see so many mommies giving their babies rice cereal to sleep even though it's not recommended? Why?

So I just found out that my husband is sleeping with my sister and they are making fun of me.

Yesterday I went out with my boyfriend went to watch a movie, me and him don't live together yet. but point is yesterday when he was dropping me off his like sleep over at my house witch the mom and dad lives. I said no,

his response was why is everyone deciding or making choices for you and their going to do the same with the baby, when I know that's not true. what he thinks is that my mom tells me not to sleep over. So he left all mad. and I felt in my heart that he went on and cheated on me...

You guys...first world problem. My parents own a rice cooker so I always just used that to make rice I’ve never made it on the stove. So now I don’t have a rice cooker to cook my damn rice and my parents are at work and unable to help me 😂😂 how tf do I make rice in the stove? Like do I just let it boil until the water is gone? Do I turn it off after it boils and let it sit? Do I turn it down after it boils? Wtf do I do?! Help 😂😭

So my “mother in law” wants me to get a DNA test,paternity test or whatever you’d like to call it done for my baby to make sure that her son is the father of my child which I have no problem with getting I understand where she’s coming from I haven’t been cheating so why not but what I wanted to know was if it was possible to get it done with me still being pregnant? so that I won’t have to deal with it at the birth if that is possible I’d like to know how to get that done without hurting our child
