Marisa was two and a half so it was a big difference in age, but I am all for children being part of the experience in some way, if you think your child can handle it. The more we are part of birth / breastfeeding / parenting especially at a younger age, the more normalised it all seems. I would agree, have a support person dedicated to Yasin, I had my sister take care of Marisa and she was great, distracting her, keeping her busy, explaining things to her. There is a great book called 'Hello Baby' which is a children's picture book, about a homebirth! It's just beautiful but great for preparing them for birth. Read as much about it as you can to him and talk about things with him too.
