Hi Karen,
Sorry I haven't responded earlier - the days seem to just fly by don't they!!
When Marcella has been unsettled I must admit that the brandy bottle didn't seem a bad idea, but I too have managed to avoid it! I have a couple of times resorted to panadol when nothing else seemed to help and that did work.....but not something to use on a daily basis. I too found that Infacol helped. Regarding food I discovered that baked beans should also be avoided!!
Now, I don't have as big a problem with Marcella as you do with Lauren, and it sounds as if you are doing all the best things, however a couple of other ideas. When you are breastfeeding, your supply is at its lowest in the afternoon/evening. That is why it is recommended to try and have a nap in the afternoon, as that will help maintain supply.....I say this as it might not just be colic that is causing the problem (by itself).
The other thing I always use with Marcie is a position thing. As we all know, babies should not be put to bed on their tummies (SIDS risk) however it is a comfortable position for babies with colic, so I often put her to sleep over my lap (head on one thigh, legs falling across the other). Quite often that will be enough to settle her, and then I pop her on her back in to bed.
My husband does the 'walk the floor' however after practice many years ago with one of his now grown up children, he puts Marcella right over his shoulder (a very bony shoulder!) so that her tummy is on his shoulder and her upper body is angled down (the pressure of his shoulder on her stomach seems to do the trick, it seems to get a burp out when nothing else will. It also helps move things at the other end - be it wind or poop). People think he is treating her like a sack of potatoes, but it does settle her.
We are very fortunate that our girl is very settled usually, but I find those tricks work. Even holding her face down with your arms like a cradle and rocking her in the air works.
Let me know how you go. I have unfortunately had to stop breastfeeding due to illness, and a dreadful supply even with all the increase supply efforts, but it is wonderful if you can keep it up.
Good luck, and I"ll try and reply earlier in future.
