yes... enjoy #1, its quite a rollercoaster . Just about to pop with #2 and its been hard looking after a toddler and being pregnant. Its not the same the second time round as you don't get the lie-ins, the pampering, the me time, you don't have the cash as you haven't been working, and you don't have the sleep when your pregnancy doesn't wake you up... your baby will.
Not so nuts - I have a 19week old DD and we are trying for No2, I can't believe we didn't do this sooner - I was the same Severe sickness until 28 weeks then instead of SPD I had premature early labour from 32 weeks and a placental abruption before DD was born a at 40+5.
Also I told my friend this recently who is ttc#2 when no1 was 4 months that a 4 mo baby is easy compared to a just walking toddler, being heavily pregnant with SPD is no joke when you have a toddler to run about after too.
