My newborn is now 3 weeks. The HV has advised she thinks he has colic and advised infacol. We have been using this but wouldn't advise of any other mothers with colic babies. How long does it take to kick in as it doesn't seem to have any affect yet. Also what about the anti colic bottles? Or the comfort milk formula? I'm prepared to try anything as it's heartbreaking watching him so uncomfortable. Thanks in advance, any advice welcome
