Raising you child bilingual does not cause speech or language delays. However, bilingual children can have speech or language delays, just as monolingual children can.
Speech and language development happens the same whether your child is exposed to one or more languages, see my previous blog "Does My Child Have a Speech or Language Delay" at https://www.VirtuallyConnectEdu/single-post/2018/07/06/Does-My-Child-Have-a-Speech-or-Language-Delay.
When looking at charts on language development make sure you include ALL the languages your child is using!
If you child has speech or language issues, it will show up in both languages. So, if you child is able to use appropriate grammar in one language, but not the other, they do not have a language delay. One language may be more developed than the other and as the second language develops further, grammatical concepts will become more advanced.
Sometimes bilingual children may mix languages or grammar rules, this is normal and will go away as the child becomes stronger in both languages. If your child has recently been exposed to a new language, they might have a period of relative "quiet" where they are absorbing the new language, this should pass in a few weeks or couple of months.
If you suspect your child does have a speech or language delay, seek help as soon as possible to avoid future issues with communication or difficulties in school.
