I would water it every day until the seeds germinate. Not just a little water but a complete drenching if there has been no rain. Use a sprinkler which gives the effect of rain, don't just hose it down. Once it has germinated you can ease off on the watering.
When you sowed your seed there was no need for fertiliser. Personally I would sprinkle compost over the seed on the bare patches and walk over it when damp to ensure contact with the soil. Time and patience are your best friends. Just keep cutting it on a high setting, don't let it dry out and eventually you will have good coverage.
