My son did the same thing. What I did was, I started breastfeeding him before giving him the solids. I also limited the solids to 1 time a day. That way he was happy and I was happy. Everyone is different though. So try different solutions that you get until you find one that works. If you don't want to limit the solids, you will most likely have to pump more often so that you don't get the overfilled breasts. I used the pumped milk for making the cereal and it worked out really well.
