I've recently returned to work and was going to put my little Cutie, who is exactly 4 months today, on formula but since I was dreading it and a nurse advised that I can actually combine the two, I decided that it was a better idea than formula feed only. So now Lil A is feeding on average five times a day and two of these (in the day time) are formula with one expressed breast milk in between. But what I've noticed is that when he was exclusively breastfed he would poo 3-4 times a day, now that he's drinking both he can go up to 2 days without doing a poo. When he does it's stinkier than before but still soft so I am not too worry about that, however I was told that if breastfeeding only then he can go up to ten days without pooing and this is normal (which he didn't) but now that he's formula fed as well I am a little worry. If anyone knows about the frequency of poo for baby who are drinking both please set my mind at ease. Thanks.
