I don't want my babies to get any older?

i just love things the way they are now, my partner has had a vasectomy so we cant have more. but my son is 2 and my daughter is 1, and i love it! everyone told me how awful it would be for me to have 2 toddlers under 3 yrs old but i truly find it wonderful and want to keep them the ages they are lol - my handsome clever little man, and my beautiful baby princess! i just want to have them just the way they are forever lol. has anyone else felt like this?
