I would have to agree with the other moms who suggest waiting a little while after he's been up. My husband and I have learned with our daughter that she really isn't hungry until she's been up for at least an hour. We used to try feeding her before we went to work and she went to daycare (family time), now we just sit her in the high chair and give her a toy and some water while mom & dad eat. Occasionaly, she will want a bite of what we're haivng, but if we put food on her tray she plays with it or ignores it. She chows once she gets to her provider's house!
We also discovered that she's really ready to feed herself, and as messy as it is--we have to let her practice with her toddler fork and spoon. She's 16 months old and has been having lots of luck with feeding herself yogurt, oatmeal, pasta with sauce (rotini works well with the toddler for), etc. Ikea sells a great long-sleeved bib that has been a blessing during this very messy time!
Good luck! Just think, one day he'll be all grown up and you'll look back on these messy days fondly!
