hi.
i am 21 and have 3 kids my youngest was born 5 weeks ago.
i just thought id say that any first time mum gets scared its normal, after all having a little baby depend on you for everything is a little daunting!
i had my first at 16 and i tbh i was absolutley petrified. all i knew was that i loved my unborn baby more than life its self.
My advice would be to accept advice from people that know what they are doing and let people support you if they are willing.
I couldnt have done it with out the help of my mum, before my first was born i had never even seen a newborn baby accept in passing let alone held and taken care of one.
when i had my second and third i was so much more confident to deal with things myself.
and of course if you ever need advice or someone to talk to all us lovley members of baby expert are here almost 24/7

good luck
Toni xx
