If your husband is an EEA national and is able to prove that he has exercised his treaty rights in the UK for 5 years your child who is born in the UK may be able to apply for British citizenship. It may or may not be a complicated application based on your particular circumstances You should seek professional assistance to make such application as its better to do it in a proper way rather than messing up the case and then seeking legal assistance to resolve it which makes the whole process more expensive and complicated.
