I follow another vlogger who had a baby girl around the same time that Sarah had Jace and she just seems so much more developed. I know babies all do things at their own time but the difference between the two babies is like night and day. This other baby is always having tummy time and is now starting to reach out for things and try rolling and has the cutest little arm and leg rolls. She just looks so much healthier and isn't constantly stuck in her car seat
