I would definitely choose something from her registry.
Does she know if it's a boy or girl?
Baby Clothes are always welcome, age appropriate educational toys, Baby bath gift sets, crib mobiles,
I love Eric Carle books, the very hungry caterpillar and very busy spider.. if they're on her list, go for them.
the nicest thing you can get for a new Mother, is to choose a gift that she will like, but even more importantly, one she will use and associate with you.
It might be best to avoid anything canine related..

If your friend wants some more suggestions on getting ready for a new baby, with a dog, there are some good links in the thread on kids and cavaliers pinned in the training section, which include book suggestions.
Im pregnant at the moment & I dont mean to sound horrible but if someone turned up to a baby shower preaching about my dogs id be more than a little offended!!
Since I announced im pregnant too many people seem to think they have the right to tell me how to manage me dogs, from not letting them on the furniture, putting them out the back & the worst was rehoming them!!!!
Im pretty sure if your friend wants some advice about her dogs she will ask.
(Again sorry if that sounds harsh!)
