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 :)

Did you have an agreement prior to having your own child? If so, you can go back and remind him about what you have agreed upon when it comes to spending time with his kids. You should come up with an agreement moving forward so you won't have any conflict on how he divides his time with the kids.
