Re: eating alot
That sounds like a funny scene at the dinner table.
Obviously there's no reason for you to give up breastfeeding and offer formula at this point. You can remind your DH that it's formula-fed babies who are at a higher risk for obesity, not the breastfed ones. My kids pediatrician made an excellent guess as to why formula-fed babies tend to pack on the pounds; she said it happens "because formula babies can walk around with a bottle hanging out of their mouth all day".
My kids were the opposite of yours: they would turn up their noses at solids until well into their second year. But babies are all over the map when it comes to solids- I have known plenty of enthusiastic eaters! And it makes sense that a not yet 1 year-old can eat as much as a much older child because the 1 year-old is growing much, much faster than the older child. Food intake tends to decline in the second year, as growth slows down. Think about it: in a baby's first year he might gain as much as 20 lbs. In his second year, he might gain only 10.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
