Dear Thunder
Assalam O Aleikum
Congratulations , I am a frequent traveller , and upon basis of my experience I would suggest that you either opt Etihaad or Emirates , as your 10 months baby will be provided with Baby Bed on these Airlines only. PIA do not care for these protocols.
Fare of these two is also cheap , and they are dead on time. Transit times are also minimum , I beleive PIA goes through either London or Manchester , and there is stay of 4 hours on Airport , that is hectic. Please check your travel agent , he will confirm you.
For DD / Funds Transfer contact Dollar East , they will assist you in getting DD
Emirates have direct flights from Multan also
Have a nice and sucessful journey
