G'day Veronica -

As Krysalyss has mentioned, the dogs won't change behaviour that much just cause there's a baby in the pram. If anything, the behaviour could be intensified due to jealousy etc.

It's worth looking at formal obedience lessons, as both you and the dog will learn together in an accelerated rate. The halti is a great tool, but does take a little while for the dog to get used to. One of my dogs just refuses to use the halti no matter what, and even the RSPCA training school gave up on him with it.

I'm not sure what kind of pram you're looking at, and the stability of said pram, but you really don't want both hands attached to dogs - if another dog were to attack or your dogs were to be scared, then you won't have any free hands for the pram. Ideally, one hand on the pram at all times, and one hand for the dogs. I use a coupling lead with my dogs if I have to, and this is working well - after about 6 months training. So I'm afraid to say that you may either be taking 2 walks a day, with one dog each time, or your DP will have to assist you.

Good luck, and HTH
