I hope I never have to use Daycare/ Nanny

I am a lonnnng way from becoming a mommy but for some reason don't understand working mothers. I have been working as a part time nanny for most of the summer for a terrific family. They have two kids ages 6 & 7 who attend camps of all sorts in the mornings and I pick them up and entertain them until their parents get off work. I feel like their parents are missing out on all their little victories and accomplishments such as being able to touch the bottom of the deep end pool or their first front flip into the pool. Things that get any child excited about. Granted, they have it pretty good in the fact that they aren't in daycare which I have never comprehended. Why would any mother have a child and then send them off to daycare and miss their first step??? I will never get this. Perhaps to make money? Well buy a smaller house and eat in more. Why even have children if you can't take care of them. I think it is pretty selfish on the parents EXCEPT of course single parents since they have no other option but to utilize daycare. I am talking about 2 parent families. Children whose mothers are their for them are going to be exposed to way more and I think have more friends since their mom can shuffle them to and from play dates. Perhaps Matt and I are biast on this since our mom's were always home when we needed them. I hope when my time comes to be a mother I can stay home and follow what I believe. We will see!
