Is there a line?
Is becoming an AB a follow on from being a DL?
When I was younger - read high school - Nappies, sure. Baby powder / cream, heck no. Plastic pants? Nope. Onesie? You must be joking. Paci? Yeah right. Crib / highchair? Running for the hills.
Now, being more mature... Yeah right.
Baby powder, cream - Yes, must use it every time, plastic pants - Sure!
Onesie - Well, at least mum will be happy i'm wearing pyjamas rather than sleeping naked. Pacis hurt my teeth - Might have to try and obtain a NUK5. Bottles? Got a horrible cold, would be nice to have something warm to drink while lying in bed.
Crib + highchair? If I was living along / significant other rather than flatting - Would be trying to build something.
So, line or blurred reality.
