This blog is all about Kaitlyn, I know. But she just keeps progressing and I keep posting about those progressions. She just hit her 5 month mark and she is sitting up awesome now and I can actually leave her alone on the floor and do chores without worrying about her falling over. She is so strong and I am so glad to see her grow and progress! She is so much fun! Way to go Kaitlyn for sitting up!
