Travelling from ABZ to RNO next March via LHR/SFO in F with BD/UA.
Since booking this, Mrs DML has fallen pregnant with our first child, due in November.
So, now I'd like them both to come with me. In F. Infant on one of our laps.
Just wanted to canvas opinion here as to what regular UA F passengers might think about a 4 month old nipper in the cabin. Is this a common enough occurrence?
Part of me thinks it might not be a good idea, but the other part (and all my friends!) say "if you can afford it and allow your family to travel in luxury, then why not?"

Would appreciate any thoughts. I won't be offended by any "anti-infant" brigades. Honest opinions on pros and cons (if anyone's done it, suffered, found it better than expected etc......parents and fellow travellers) would be most appreciated.

It'll help me make my mind up on what to do. Thanks
