Second born

I have a 14 month old son and I’m 13+5 with my second. Most days I don’t even think about being pregnant. I’m happy, nervous, excited. But if we’re being honest it doesn’t feel real. I had four miscarriages and was ttc for a year before I got pregnant with my son and I remember it not feeling real for a long time. But this time it’s like I’m so busy running after a toddler and trying to get all the naps I can (because my son doesn’t sleep through the night yet 😅) that I just feel distracted and forget I’m growing a whole second child. Anyone else? What can I do?
