I noticed that my husband spend more time with his other child than our own child lately, so I plan to confront him one of these days . How would i do it ? Is it advisable to confront him and demand more time with us ?

Confront him in a nice way yesha , theres no problem that cant be solve with a calm and proper communication . Yeah you can demand time of course but see to it that no one will be affected . Please understand also that his child needs care of a father and likewise yours too. Proper time management maybe would be the best advise for your husband so that attention will be fair. One last thing confront your husband in a right timing where he is in a good mood :)
