You should be dedicated, and you can do protection on yourselves and each other.
As for your baby - you can vibrate the Rune BJÖRK - "This rune can be used in workings for female fertility, feminine magick, and nurturing. It is used in concealment and protection. This rune symbolizes feminine energies. It is an old Pagan custom to enclose a child at birth with the protective energies of Berkano, which remain with him/her throughout his/her life.".
If you want to protect each member of your family, you should work on each of them individually. You might start your own familial coven, and raise energies together, but working on each person must be done individually. Each person can use their own protections to protect themselves and each other, and also your pets and the property.
