G'day everyone,, firstly I have to apologize if I am posting in th incorect section... Anayway so I have a little baby kid I am feeding of th bottle,, actually I have two twins.. One of thin is powering on no problems,, however the slightly smaller one seems to have a problem.. Problem is every 7 days or so he gets a really bloted stomach and doesn't eat for a day or so and becomes very larthargic,, has anyone ever experienced anything like this??? & maybe knows what is happening & what I sholud do?? Regards. Jason.
