Question for those with 2 or more kids...

Do you ever regret having more than one child or do you just adjust to the new normal and cant see your life without all of your kids? The reason im asking is because Im pregnant with #2 but i am scared that i wont be able to love this baby as much, or that i will be too busy to give my other baby the attention she deserves. Any insight you can give to put my mind at ease would be great. Thanks!
