Baby carrier, all the way. Your baby at a few weeks old will not learn to only want to be held later on. Even carrying the baby all day at 3,4 or 5 months old will not result in a needy helpless child. It will make your life WAY EASIER. Baby will be calm, happy and protected and you will be free to work with the other children without having to worry about baby's safety.

Once baby is older and the others have adapted to babes presence then you can start putting baby down for chunks of the day.
