Health nurses had told me that on average he should be eating about a cup at a meal now he is probably having half or just over that which is why I was starting to stress a little bit.

Lisa what fillings do you put in your sandwiches? He will eat sandwiches but so far have only put cream cheese on them. I make them small about a finger wide each way as he stuffs them into his mouth. He will eat up to 5-7 of these. I found the avocado ones got a bit soggy? Also what size do you cut up the veggies/pieces of meat. Again he is inclined to stuff the entire thing into his mouth so didn't want to have them too big as I though it might be too difficult for him to chew. What other finger food suggestions would you have? I am quite happy to cook for him my hubbie and I don't eat until after he has gone to bed as DH just wouldn't get home from work to eat earlier.

Kim I try to offer variety though brekkie probably just alternates between cereal and scrambled eggs with yogart as chaser if he will have it.
My DS is 13 months and definately doesn't eat a cup at each meal, we're lucky if it is a half a cup. I've also worried about him not eating enough, but he is gaining weight fine, so I think it's more my expectation that is out of whack iykwim...

My DS also doesn't like to be fed by spoon, mind you now that he is slowly starting to get more coordinated and can do it himself this is changing. But when he was your LO's age he wouldn't touch a spoon. Finger foods that I find great are sausages cut up into little peices (very easy to chew), fish, quiche, toast, sausage roll etc. For brekky he has toast (sometimes with cream cheese, which he loves, or vegemite), raisin toast is also good, wheat bix, cut up fruit and a yoghurt (the squeezy ones a great when they don't like spoons) and occasionally an omlette packed with veggies and a bit of ham (this is also a good dinner or lunch). He also loves cream cheese sandwhichs, cream cheese and avocadoe is a good combo, otherwise I will do tuna with cream cheese and sometimes I'll even mash up some vegies and put it on a sandwhich with cream cheese.
