Pronouncing "ch" and "sh" - please help!

[cuzzy01]

Hi, for years i've had trouble pronouncing the sounds "ch" and "sh" and it's been rather annoying, i was wondering if you anyone could help me and show me a method on how to pronounce it properly, when i say "rich", "wish","riches","wretched","chips","chicken", words such as them the air comes from the side of my mouth rather than straight through the middle, so "ch" becomes "sch" for example. If anyone can help, id really appreciate it

thank you

maybe trying to put your teeth together in the front would focus the sound to come out from that area instead of coming out the sides of your mouth. Like putting your lips together and focusing on that at first until the sounds start coming out right and then you could focus on how you look after that.
