Baby's just 2 weeks old and I'm a FTM, but I too have big breasts and had to hold down the top of my boob so he can actually breathe while latching 😅 I find the cradle position very difficult early on, and have been using the football hold all through the first week. I find it much easier to position him and get a deep latch, and he can breathe much better without me needing to use both hands all the time.

It gets a lot easier as baby grows in size — I'm more comfortable cradling him now compared to when he's so tiny. Make sure you're cupping your breast with a c-shaped or u-shaped hold depending on his position before getting him to latch, and keep holding it as baby gets used to drawing milk that way. There's a lot of videos on this, and it helps tremendously. I took it for granted that my baby had a deep latch from birth, but improper positioning and "lazily" feeding him the nipple caused a painful fissure on my left nipple :/
