OP,
He sounds like a good man trying his best.
But sitying under a baby constantly is exhausting.
Every time any cooking is done, do treble.
Be it simple mince, a pasta sauce, a curry, treble the amount and freeze.
Have plenty of beans, eggs and bread in the freezer.
Beans on hot buttered toast, topped with cheese and a egg was a very nourishing tasty bite.
Waffles with the above are delicious.
Make sure you are drinking enough water.
Have it close to hand.
Dehydration is a big thing with new breastfeeding mums and it makes you feel more tired and head achy.
Have some protein bars in the house so that you can have something quick on the go.
I loved fig rolls.
Also I used to make a power smoothie.
Full of orange juice, bananas,protein powder, berries and cod liver oil.
Very filling and nutritious and could be drank in seconds.
Food on the go is important.
Mind yourself, it gets easier.
Oh and accept ANY offers of a meal!
