Fussy baby 2.5 week old

I have a 2.5 weeks old and he gets gassy and has acid reflux most of the days.

We are giving gas drops for him and also making him burp every often

But still he has gas and cries and is fussy. Is it normal ?

Is is giving gripe water safe ?
coz of his reflux can he sleep for few hours elevated in fisherprice swing or car seat.
