Hi, I am a Wind Guru 
My 2 (now 3 and 1) both had reflux. Very similar in some ways to colic, infact colic is one of the symptoms.
For wind I swear, sleeping them on their tummy's really help. Something like 95/97% of cot deaths are in homes of smokers so don't panic at the thought.
It really helps soothe their stomachs, aids digestion, stops the startle reflex wakening them in the first place and you will hear them trumping all that gas out while they
sleep
!
Get a sensor pad monitor if the thought unsettles you. Even just try it during the day naps.
Infacol/gripe water/every kind of tea known to man, done nothing for mine but as I said, they also had reflux.
Also, keep an eye on them for arching their backs whilst feeding, pulling away, over fussy feeding. That's the main sign of reflux and it is very common.
Some are sick, some are not. Some loose weight with poor feeding and some FEEEEEED all day and night and puff out like little balls super quick as the breast milk has an instant antacid relief for them. I had one of each, I know, lucky me!
Over feeding a colic/reflux baby makes for really bad colic and wind especially in the evenings.
Try spacing the feeds out so that they have had AT LEAST 2 hours to digest the last feed or they will have terrible pain and wind. I used to walk up and down with the hairdryer on for white noise
. Get my DH to walk, any random visitor just so my over feeding DD would wait at least 2 hours for the next feed.
Good luck and and please remember, it all dies down by 12 weeks and you will survive it!
