Hi...bubs is 8.5mths old. I am going back to work in January so have to convert to some formula feeds (expressing takes forever and I just can't get enough). I am dropping the lunch time feed next week and going to replace it with formula (as DH is on holidays to support). What formula do you recommend? Bubs has had constipation issues in the past so would love recommendations with that in mind! Thanks for your help!
