I would advise insistence on both being gentl with each other, but otherwise allowing the dog to be around the babe. Of course they should be parted if either gets overwrought or when you cannot watch them.
My daughter was a toddler wehn I had my first dog a BSD and they were inseperble though she couldn't cope with kids enmasse, and was never allowed to run around with them if they were playing, had to come lie down by me.
When she died my son was a toddler, and my Elkhound pup had to be restrained from kncoking himover, so only got petted in the down position. The Elkhounds have not been as sensitive as the BSD was and can handle kids very well, but again I would never leave them alone with a very young child for the dogs protection :D
My freinds Grandaughter learnt to walk holding onto teo of mine and laso the family Golden Retriever.
