Is this normal? Another poop question

[Hotmad]

My 2 month old went from popping once a day to now like 4 or 5 big poops a day in the last 2 weeks this is coinciding with going from breastfed to formula ( I do still give 1 or 2 breastfeeds a day) she also has become very sicky and what seems to be reflux although one dr days it is and one says not.
The poop is not runnier than ever before, soft and yellowy, has like bits of small whitish particles to it too... Normal or not?

Yellow with seed like white thing is normal. Yes four or five a day is normal I think. My DC2 then went to one every 6 days.....eek, but even that is normal for Ebf.
