Well I hope my post is not regarded as sexist...
I think what you do Christopher is awesome..so I also hope you don't take my post as questioning your role in your sons life.
Yet I feel for the first year that ultimately a child should be with it's mother. I understand that many family situations do not allow this and I do not condemn any one for having to do what best suits their family's needs. I just feel that nature has instilled a very special bond between mother and child and that is why not only do babies suffer from this separation but many woman do too. I am also a very big proponent of breastfeeding..and I think a child should be breastfed for at least a yr

I suppose I am very much a traditionalist in regards to this issue and I am ok with that. I do only feel this way in regards to the baby in the first yr..I think mostly I feel this way because physically men can not breastfeed and men do not carry the baby around for 260something days and men do not give birth to the baby.
I think afterwards which sex is the prime caregiver does not matter. I understand that a lot of woman would not make better caregivers than their spouse, do not want to breastfeed their child and do not want to stay at home. I just personally feel that this little set-up mother nature has is truly the best one for baby and mama and I completely understand that is just my little view on life and don't expect anyone else to believe it or adhere to it.
My husband misses his children horribly and he often does wish he could be at home with them more..and he is often jealous of the time and different life I have with them. So I also recognize that it is just as hard on the males...I just think in a different way.
So yes I think it makes a difference who is at home with the child..and I think it does effect the child differently.
I also think the decision should be based on the needs and restraints of the family itself. You can not just make a blanket statement...it should always be _____ reason in deciding who will be the main caregiver because every family is different and has different factors and beliefs to consider.
Christopher I just bought my kids the new TMBG CD ..it is a kid's CD..all kid's music and my two love it...I highly recommend it. It is kinda like kid punk rock.
