Fussy fussy baby

Dannielle

So my little guy is 11W +2.

This week he's turned super clingy, sleepy, barely staying away for more past an hour.

He sleeps perfect at night and is feeding his normal amount (he put himself into a feeding routine of exactly ever four hours and sleeps from 9pm till 5/6 which has all been okied by my health visitor) and usually he's quite a happy little guy and stays awake for a bit in-between naps.

Took his temp etc and he's fine.

Anyone else experienced this, any advice on what to do?
