Accommodation requirements for dependant children

Good evening everyone ,I am a british citizen and I brought my wife on spouse visa in 2020,and she already got 2 children age 7 and 4 before she came to uk ,now she has another child in uk now .now the question is can I bring the 2 children in to uk as I have 1 bedroom flat with separate standard living room which I plan to turn to their room ,will that be enough to meet accommodation requirements,thank you all

Are the older children your children or are they from a previous relationship your wife had?
