MOTN feedings AGAIN!?

Roxanne
My little girl has been sleeping well at night with frequent wakings just for paci but for the past three nights she's been snacking 3 o around 3 am because she won't go back to sleep otherwise!! I don't know whats going on. Is it because I started her in solids??? I don't want her to get used to eating at night again! She's 19 weeks today.
