Well it partly depends the age of your child.
If it is only a infant, you can and your family and other people that see your child can learn you child english, by speaking to the child in english on a daily basis. also if your child is a little older, at nursery for example- they can provide services to help with your child's speech, language and communication.
like the other person said it depends on their age. all you can do is expose them to the english language through books, you talking to them. as long as they hear english they will be able to speak it.
