Pink sleepsuits- so what!?

So recently had my 2nd child a baby boy.

My first born is a girl.

Kept all her clothes and what is suitable to be used for the boy I am using it.

Most of her sleepsuits were pink, with hearts on or pussycats.

Today AGAIN my friend mentioned how can I keep him in a pink heart sleepsuit!?

I'm like he has boy outfits for going out but for sleeping what difference makes a colour!?

I'd be mad to buy new ones for the 2 months that he is wearing them in the first few months!

So annoyed!

Guess I am not the only one who does this!?
