My granddaughter was born at 34 weeks 7/8/22, she is now home (original due date 8/19/22. She’s doing great, however she does a lot of grunting, gets really gassy, then becomes very cranky. Not necessarily crying, just more fussy, difficulties sleeping. My daughter has been using the baby gas drops. All that junk they put into stuff, I’d like to find some type of a tea, or glycerine tincture.. my concerns with the tea is that it doesn’t last long. Let me know thoughts… and recommendations.
