After revealing in August that she was expecting once again, Bachelorette star Emily Maynard gave birth to her fourth child on Sunday, an occasion that husband Tyler Johnson excitedly shared in a series of Instagram stories.

Throughout the day, Johnson posted several updates from the hospital, starting with a smiling selfie of the two of them as his wife prepared to give birth. The follow-up was an adorable video of their new arrival.

鈥淣umber four here!鈥 the caption read as Maynard was wheeled by in her hospital bed, looking radiant with her bundled-up new baby in her arms.

The new addition makes it three under three (and four total) for the happy couple 鈥 they also share sons Jennings Tyler, two, and Gibson Kyle, one. Maynard鈥檚 12-year-old daughter (from her relationship with her late fianc茅, Ricky Hendrick) was also at the hospital, and Johnson shared a sweet look at her meeting her brand-new sibling.

So far, they haven鈥檛 confirmed any additional details, including the baby鈥檚 sex or name. The Bachelorette season eight star previously revealed that she needed a scary emergency appendix surgery when she was six months along, so we hope the rest of the pregnancy and delivery were smooth sailing.
