Nik evan without the ILR your husband can claim child benifit and tax credits, its just that can't, but I believe once you receive your ILR you can also receive benifits as the no recouse to public funds will be lifted so you can claim in your own right.
The child benifit your husband can claim regardless for the baby, but the tax credits you have to a see how much your both earning to be entitled to them.
Good luck Monday
