What would you do... inlaw trouble....?

In-laws can be difficult and you should not have to deal with this type of crap while being pregnant. Your husband has to realize that when he married you he left his old life behind and needs to stand up to his parents. I have had to do it for my wife. If they want to be childish then they need to realize that this is your family first and that they have to respect that. talk to you husband and CONGRATS on the baby.
