I seen a crochet pattern for baby that was a changing pad set and can’t seem to find where I saw it. Could use some information if someone knows about this.

I first had my 2 month old on formula and her stool was dark green and very thick, the doctor said to put her on lactose free milk for about 3 weeks so her digestive system could get use to the milk. She was on this for a month and her stool was yellowish (normal) when I went back to the doctor 3 days ago she said it is time to put her back on normal formula. Since today again she has got dark green stool and very thick, does that now mean she is lactoce intolerent, cause on lactose free she is fine and on normal her stool changes again?

I asked earlier today whether I should try convert my 5mth old to normal milk as I have heard it is bad to keep them on lactose free. I know now that it wont effect how he handles lactose later if I stay with the lactose free stuff, but I do want to change him over onto normal milk based formula (mainly as there is only 2 places in town I can get his lactose free stuff and its expensive).
Should I just switch it altogether at once, or do it gradually?
Of course if he doesnt go well with it, I will go back to lactose free…
