decreased appetite in my 7 week old: Please help!!

[Wsandy]

Hi all yesterday we made the switch from aptamil advance to normal aptamil, shes 7 weeks old and ive noticed shes bottle and breast feeding less. Shes probably had about 9/10 of formula since 5 this morning and shes been on and off breast but not very long each time. Shes still having wet and dirty nappies, she doesn't have any dehydration symptoms, just wondering if this could be the formula change or if its something else going on. I havent called 111 yet as she doesnt normally have a big feed in an hour and i want to see if she does this before contacting them and maybe taking her out into the cold. Really appreciate any help or advice

The main measure of how much is going in is how many wet and dirty nappies you're getting. If they are normal then I wouldn't be worried.

I think im a bit concerned as well as it seems like shes a bit sleepier and not crying as much but shes definitely having a good amount of wet and dirty nappies so thats good to hear

My DS had periods like that. Usually around some sort of developmental milestone/ growth spurt (I know, counter intuitive). It would last a couple of days at most and then go back to feeding normally
