The second picture also included the ultrasound photos that proved there is, indeed, a bun in the oven. In the caption, Rebecca wrote: ‘Here comes the sun. It has been a very humbling journey for us since October and a rollercoaster ride in the past couple of weeks ( will share more on that later ) but through every single obstacle we continue to see God’s goodness through our growing miracle.’ She went on to thank fans and loved ones for all of their love and support and sent them ‘love, prayers, and encouragements.’ In the meantime, John shared pics of the growing family as well, captioning the post with: ‘Blessed and Excited.’ It is safe to say that the reality TV family has grown a lot in the last year.
