I basically do what skinny love bc does: make a cup of tea, give the baby 2 oz and drink the rest. He does seem to wake up a little less, and I feel more relaxed. Some kids just aren't good sleepers--mine isn't. About 4 years ago I saw they had done a study on the efficacy of chamomile on reducing colic, and it did reduce the crying. I use it when the kids are miserable, teething, or out of sorts. Seems to help and it's gentle.
