If you are all living together as a family, the child can be entered on only ONE tax return. If the bio-dad is claiming the child, then that is the only tax return on which information about that child can be entered. The other parent can file Single, and will not enter anything at all about the child on their tax return.
The parent who is claiming the child can file as Head of Household, and may be able to get the other child-related credits such as the childcare credit, child tax credit and earned income credit. And of course, you can claim medical expenses PAID in 2022 for the child if you itemize deductions.
You cannot claim anything for the "day to day" expenses/items for your child. Those expenses are not deductible.
If you hire a nanny in the future, the nanny may be a household employee if the nanny works in your home and earns $2300 or more in the year. You will need to issue a W-2 and withhold Social Security, Medicare and federal tax from the nanny's pay.
