I need to gain, fast!

Ev

Hi everyone! I'm 30 weeks with my first. I started out just under 110lbs and I'm now almost 130. Not a ton of gain for someone underweight :/ my baby is just a bit behind and I'm planning a home water birth so I really want her to be a good size and to stay put until I'm due (I know being underweight puts me at risk of an early labour)

Quick tips on how to gain a few extra pounds in the next 2 months?!

TIA!
