BABY UPDATES
In April, Amy gave an update on her pregnancy journey as fans worried about the TV star's health.
Previously, the star shed 136 pounds to safely give birth to her firstborn son, who is now one.
Upon reaching her 27-week mile-marker, the 32-year-old wanted to celebrate her progress.
She posted on Instagram: "27 weeks baby!!!"
Amy shared a graphic from an app of the baby's progress at the nearly seven-month mark, revealing the child is now approximately 14-and-a-half inches head to toe and weighs two pounds.
The TLC star also added an explanation about the boy's development.
The update read: "Your baby's eyelids, which have been fused shut, can now open and close, and she may blink in response to light."
It continued: "If you shine a flashlight at your tummy, you may feel her respond with a burst of flutters and wiggles."
Amy also shared: "Chalk up any tiny rhythmic movements you may be feeling to a case of baby hiccups, which may be common from now on."
Amy previously revealed to The Sun exclusively that while she has cut back on cigarettes during her pregnancy, she is still smoking.
The reality star also noted that she has been eating healthier.
Amy told The Sun: "I'm not drinking alcohol. I used to smoke a pack of cigarettes a day, like 20, now I'm down to about five a day. I'm trying to cut down."
She added: "I feel like I'm actually losing weight with this baby because I'm eating right."
Amy shared: "Gage's favorite foods are green beans, broccoli, brussels sprouts, and tuna fish. That boy will eat tuna salad every day if I let him.
"He eats healthy so I eat healthily. But I do have sugar here just in case my sugar gets low, because with this baby my sugar drops into the 40s, with Gage it was always high."
The star concluded: "I asked my doctor, 'Hey is it okay if I lose weight.' And my doctor said yes, as long as the baby gains it."
