Milk brands 🤔

Hi ladies. I am currently pregnant with my 2nd child. I struggled to breast feed my first and so i know this baby will be formula fed. With my daughter we used aptimal and never had a problem with it, however I am currently looking around at milk types. What is everyone thoughts on the Aldi powder? We use the nappies, food and bath stuff ect but for some reason we never used the milk for our daughter. I have heard people say that their children have become constipated from using the Aldi milk, but I would like to have a few different views. Sorry for the long post, but any view would be appreciate (good or bad!) thank you xx
