Dairy products Milk, yoghurt, ice cream, cheese, and the likes i.e. dairy products generally can be constipating if your consumption of these is too high. More than adults, these affect children adversely. This of course does not imply that you stop consuming dairy products altogether. Intake of dairy products in moderate quantities is alright, and in fact, it is desirable. Instead of milk, you might want to go for almond milk as it contains some amount of fibre that will work well for your system.
