Motherly instincts will kick in once you have the baby. You'll be breatfeeding and changing diapers like a pro. You'll really be surprised by yourself
I don't think anyone goes into labor thinking "well I'm totally prepared for this baby". I definitely didn't with my first and I definitely don't feel that way close to my due date this time. There's so much uncertainty and variables that go into having a baby. Even when she came the day we took her home from the hospital I cried because I didn't know what in the world to do with her. That feeling lasted all of maybe a week (and that's a heavy maybe). You very quickly adjust and get into the swing of things, if I'm honest we over prepared and had a bunch of useless junk we never used. You've already got experience with children, and while you didn't birth him, it's the same thing, caring, feeding, clothing, playing, loving him. In fact you might be surprised with how little your baby needs in the beginning, how easy it is to just strap them to you and get some things done.
I'd say you worrying about it is a great sign, and while I know it won't help, try not to stress. No one is ever really ready, but if you know you at least have the necessities, then you're good. Good luck!
Sorry i wrote wrong is your step son no your niece...also if your going through many things try to get all help you can and maybe taking some time for yourself will be good.
Its ok....i can understand u maybe at this point there is no words to make u feel befter but the fact you concerned still true....you gonna be awesome....im 27 weeks and have an older boy so i make the same question every single day...sometimes im very stressful thinking if im doing good or what can i do to be better but inside me im sure im a good mom....my advice is just look at your beautiful niece and your baby and think God select u to be their mom cuz he knows you're good....everytbing gonna be fine...for good momies never is enough you no along in this.
Just cuz you're concerned means you gonna be a wonderful mom....bad womans dont care about so im sure you will be the perfect mom for your baby....all those fellings are normal honey.....enjoy your blessing ..
