I just went on a 6 hour flight with 2 layovers by myself with a 5 month old. BF pretty much saved my life during that trip. My son HATES to be constrained. His threshold for holding is like 30 minutes max, so needless to say, 30 minutes into our trip we had a major meltdown. Combined that with being overtired and you have a nightmare situation! It was so nice to just pop him on and lull him to sleep or just calm him down whenever I needed to. I nursed him when he was tired, anxious & hungry and helped make the trip a pleasant one.
Here is what worked for me:
1) The window seat worked out much better for us. I could BF discreetly by turning into the window. My LO HATES covers, and while we had to use them a few times when I was seated in places where I could be seen, it was much easier to just lean into the window where nobody knew what was going on.
2) Nurse in the baby carrier. I have an ERGO and it was a massive help during layovers. I would simply latch him on as we were deplaning and nurse him while connecting flights. In fact, on our last connection he nursed in the ergo, fell asleep and I left him in the ergo the whole 2 hour flight (getting my seat belt on w/o waking him was a miracle!).
BF was our secret travel weapon….I had a generally calm baby the whole way thanks to nursing.
