However, over the last few days, she's developed something of a habit of vomiting all over Mummy.
Initially, we weren't too concerned. But yesterday, Vanessa gave the midwife a ring to explain what's been happening and ask if there may be a problem.
And there is a problem - a drink problem.
In fact, the greedy mare can't get enough of it.
Rather than take enough milk to do her, it appears she simply keeps going until she pops/barfs/wretches/hueys/spews.
Or, to put it another way, she's a binge drinker.
I can't describe the family shame.
