Baby has reduced daily intake by about 5-10oz

My son will be 5 months next week. He's a big baby (9lbs 9oz) at birth. He was taking roughly 5 7oz feeds a day but about 10 days ago he seems to have lost his appetite. He's been taking between about 24-28oz daily instead of the usual 32-35oz that he was taking.

Has anyone else's baby done this? I've not started weaning him yet. He's just not interested. He doesn't appear to be un well. He is teething but isn't overly bothered by it and is still sleeping well.

Some people have said he's loosing interest in milk and looking for solids but I don't think this is right?
