when i first started giving sam solids, i would express some breast milk and then give it to him in-between spoons of solids, but i gave that up as all that expressing was such a pain. so then, i would give him one boob (i.e. half a feed) and then solids, about 40 minutes later, and then the other boob just before his nap, but i stopped doing that when sam started refusing his breakfast! now, i give him solids first thing after i change him and then wait a while (about 30 mins) and give him one boob and then give him another just before his nap, which seems to work for us. so, i guess you just have to try different combinations for a while and see which suits you both and be prepared to change as they change?
