7mo eats all day and only wants milk at night! help!!

[somesunshineplease]

She has been sleeping from 7-6 for 2 months including during a 3 week overseas trip, went off food altogether a few days ago due to teething, now is eating food for the world side during the day and waking up 2 or 3 times at night to drain 8oz bottles of milk!! Is this is growth spurt (and will it be over soon?) or do I need to give her less food during the day so she drinks more milk during the day and less at night? I'm going back to work in a few days and feeling shattered....
