I felt the same when I started my son on solids, was not sure what the amount was, and than when I added the breastmilk it became realy watery. Found out later it has to do with the enzymes in your milk breaking down the cereal........ I made it with cooled boiled water after that, much better consistency!
My son has three meals a day goes something like this:
7am bfeed
9am cereal with water to drink
9.30-11am nap
12noon dinner 3/4cubes of veggies with chicken and one cube of fruit puree, water to drink
3pm bfeed
3.30-4.15ísh nap
6pm pureed fruit with baby rice/ or maybe baby yoghurt 9the ones made with formula) he used to have a bfeed after tea, just dropped that yesterday
7.30pm bfeed
8.00pm bed (sleeps through the night has done since he was 6 weeks)
I seems to work for us, have been concerned with dropping feeds down to three, but health nurse seems happy. My son is 5 months 2 days old and is 19lbs 11.5ozs (well was that weight 2 weeks ago), he was almost 10lbs born. He doesn't seem huge though, is very long. I have a high metabolism myself so perhas he inherited that. He lets me know though if he doesn't like something or has had enough.
