Jackie • 24 y/o Jake G 💍 mama to LNG 4/21/17 👶💙. SAHM . Idgaf about your opinion. It doesn't phase me🙌I say whats on my mind. Gtfo my page if your a hater. I don't need that type of drama. Stay blessed . 🙏🏻
So today I've noticed baby hiccuped at two different times. In the morning he hiccuped for 5 mins then it went away. The second time he started hiccuping it lasted for about 15-20 mins should I be worried?
