V was only BF until 4 weeks and then FF from then on.....she didnt satart sleeping thor\\rough until well after 2
M was BF until 7 1/2months and yes he had a top up of formula at night in the end and he slept 15 hours.

I really dont think it matters if you BF or FF...if your baby wants some TLC though the night their going to let you know. Hasnt DH realised every child is differnet and cause of that their need's are different?

hon. Follow your gutt..its hasnt told you wrong yet
