A suggestion: you might want to start a post for tips for being a parent of a toddler while frequent breastfeeding for ideas like the one about the sling. A lot of people have been through that! Maybe a heart to heart with your man would be helpful about his expectation of dinner when there's a nursing baby in the house, or, some moms put dinner in a crockpot at breakfast time and then it's dealt with.
About whether it's normal and why:
Yes it is most likely a growth spurt.
Breastfeeding is an amazing mechanism that allows a baby to regulate their heartbeat, breathing, temperature, antibodies they need to fight illness, and pain relief from endorphins! So there are "frequency days" (and weeks) like this that are completely normal.
Whatever the reason (probably a growth spurt) this is normal. It's also normal for you to feel burned out.
When they get older there are more reasons, hitting milestones (sometimes they pratice muscle movements in their sleep like crawling!) teething pain...
It's all normal.
It's good exercise for their jaw and mouth development too. BF babies are less likely to need braces or speech therapy.
