Hi,
my 9 month old little one suffered terribly from constipation once we started solids. I even had to resort to giving him a suppository....twice!! I have no clear cut solution but I have done the following which seems to have alleviated his constipation. At least he goes every day now without too much straining...
* No bananas. I was told that bananas actually make the constipation worse.
* No carrots. Same reason as with bananas.
* Prunes. I have starting buying dried prunes, which I boil in water for about 15 mins, and then puree. I freeze the puree in an ice block tray and pop out a cube every morning, heat it up and give it to him before his cereal in the mornings.
* Stopped taking my pregnancy multi-vitamin. Someone advised that perhaps the iron in the tablets comes through in my breastmilk and adds to the constipation. Just have to be extra careful with my own diet to keep up my energy levels while I am breastfeeding.
* Spinach. I feed my little one lots of spinach. I actually make a spinach lasagne for the whole family and before putting the lasagne together, put aside some of the spinach filling and he loves it. I also mix it with a little tomato sugo before feeding it to him.
* Water. I give my little one lots of water in sips throughout the day.
I'm not sure which one of the above has made the difference, or whether it is a combination, but I have introduced these five things over the last 2 weeks and there has been a marked improvement with his constipation.
Hope this helps
