Why do i feel like im stilll living in a dream?😕

So i had my 1st baby in 2020 hes 2 now. And my 2nd this year in March… i can’t believe they are mine still like it hasnt sunk in that they are mine my kids… i feel like they arent mine like its crazy i gave birth to them.. 😭 i feel delusional… like idk why i cant wrap my head around me having kids .. is this a normal feeling? And time goes fast to see them grow up already my daughter is 8 months old .. like how does time fly? Feels like i just gave birth and it also feels like it was all a blurrrrrr when i gave birth and had them
