Any more baby advice cause I am pregnant!!!

I am 21 years old, and I have three children. I got pregnant with my first when I was 15 I was very young, and scared but I pulled through and tried for 2 and 3. I won’t lie my first was very frustrating but I wasn’t the kind of girl who’s mom would do it for me.”not that I ever would have wanted her to” but I wasn’t ready to be a mom, being up all night definitely did me in… But that’s simply one con, the pros are endless, you have no idea what the word love means untill you see your child for the first time. The biggest pro of all… Is I never got mixed into the wrong crowed because I had to be home. So I read the weekly police log, and may notice some names of people I use to know, or even once was friends with but it makes me happy to know that its not me, that even though my mother was as scared as I was, when we found out. Today she is proud of the woman I became, and the mother I am, I am so content with my life, and can say that when I was 15 years old, the best thing that could have happened to be did. And thank god everyday for helping me stay safe and away from drugs and trouble.think possitive don’t let anybody bring you down. Keep your chin up… Oh and by the way. Congratulations!
