Why am I the only one who tries to discipline our toddler?

hunni.. your going to need to sit him down and tell him how u feel not argue really tell him.. i mean this is very important that u keep to your guns.. what your doing is best for your daughter and if your partner is going against that she obv sees this and gets fun out of it.. although it may be hard for him if u r the main carer maybe time spent with his daughter he just wants to play with her and spoil her as all daddys do...u need to explain to him how important it is and how much it upsets you when he does this.. also make sure the 3 of u have sometime together were yous can make lots of mess and have lots of fun and sillyness so she can be "" in a good way!
