Plastering & Rendering

My baby's crying is disturbing neighbours - how do I soundproof cheaply?

I live in a very old house (c. 1750) which has thin walls between the properties. (I don't know what type of walls they are.) As a result, my neighbours can hear the sound of my son when he wakes in the night, which is only for a few minutes at a time but can be a few times each night, and they are at the end of their tether from sleeplessness. Their bedroom adjoins ours, not his. There are only the 2 bedrooms upstairs. We'd like to end their suffering by installing soundproofing - but don't want to break the bank - plus our bedrooms are very small so we don't want to eat into them too much. We've heard of a product from the US called Green Glue, which can be applied to plasterboard. Does anyone have experience of using it? Would we need 2 layers of plasterboard to reduce the noise to a barely audible level, or would 1 layer do it? Would we need both rooms done or just our son's? - and party wall only or internal wall too? Would a plasterer be the best person to do this work? And roughly what would it cost? Many thanks for your help.
