This is about more than food. Your daughter is most likely missing having you around all the time, and enjoys her special time with you during the night. It is really common for breastfed babies to start nursing even more frequently during the night once their moms go back to work, as a way to reconnect. It's great that your dh wants to help, but it's not really help if you just end up being awake listening to her scream. I'd have her sleep nearby so that it's relatively easy to nurse her. If you're comfortable putting her in bed with you, that's the easiest. Cosleeping has saved many a working mom!
I also wanted to comment that adding rice cereal to her breastmilk isn't really helpful, and at that age is against the recommendations of the AAP. The current recommendation is exclusive breastfeeding until at least 6 months of age, and starting solids at some point during the second half of the first year.
