puppy jealous of newborn

Question
We have a 10 month old female maltese terrier puppy.  My daughter recently had a baby and when she comes to visit, the puppy poops in a bedroom like she's jealous of the infant.  Other than that she is crate trained and goes outside.  How do we discipline/train her/scold her to stop doing this?

Answer
Hmmm the little monkey well she is trying to be dominant when the baby is there do the same as normal training pick her up say NO firmly and place in crate for 5 mins and repeat hopefully!! eventually he will relate the behaviour to being banished to the crate lol and will stop
Good look anyway
