the order of events is fine so long as you do not feed to sleep (which you aren't)
my only ocncern woudl be that at 10 weeks is lo getting enough food in the daytime if you feed every 5 hrs. are you BF or FF? if lo goes 5 hrs does intake increase at the next feed? if intake does not increase substantially you would probably be better off making sure to offer the feeds 3-4 hourly. if you want more specific feeding advic eyou can check with the releavnt moderators (BF or bottle feeding boards)
