Trying to get more food into a baby

I went to the plunket family centre today to get Josh weighed (just for me to see how he is going) and he has lost weight. So not what we were expecting. The plunket nurse told me to start solids but here's the problem - Josh isn't interested in eating food at the moment, I put the spoon in his mouth and he pushes it back out again. Should I just let it be and leave the solids thing and just wait and see what happens next monday when he gets weighed again, or try and get some food into him.

I'm with Teresa, don't rush into solids if he's not keen. I tried that with Maya just coz her weight gain had slowed and it didn't solve the problem. Maybe try some of the ideas to boost up your breastmilk or *shudder* try one bottle of formula a day to up his calorie intake.

My gremlins are still tiny eaters, they share one tin of food between them and sometimes don't even finish that, yet Maya at the same age would have 2 tins plus some crackers or toast.

Do you think your milk supply may have gone down? Is he feeding as well as he used to?
Gina has had a few days where she's eaten hardly anything - in fact I was so worried I took her to the GP - nothing wrong thankfully. Of course I know how much she eats as I feed her EBM. My milk supply has gone down lately but I figured it's because I've been quite busy so not eating as well + I express full time so was blaming on that.
Can you give him solids thru a bottle or are Plunket suggesting solids to avoid giving bottle? I've been thinking on getting Gina started on something like this maybe but I'm def waiting until she's 6 months - she shows no interest in solids yet.
