I feel like I’m giving my newborn son too much attention rather than my 4 year old daughter

So my son is 5 days old and I’m in complete awe i am obsessed with him. With my daughter i had postpartum depression and i never felt this with her until she was older and was on medication for my depression. I feel guilty enjoying my son as i wasn’t able to enjoy my daughter as a baby. She is the sweetest little girl and i do what i can to give her attention but sometimes i feel like it might not be enough. She’s fine and shows no signs of jealousy but i think i just feels guilty in general that i am enjoying my son since i didn’t get postpartum depression.

I do what i can to give her attention but she’s at the stage where she like playing alone and doing her own thing . She’s fine and shows no signs of jealousy but i think it’s just me feeling the guilt . Should i be feeling this way?
