Oh dear! This is not good, so she presumably wants to look after him for the three days that way she’s the only one looking after him, what on earth is she talking about it saying it is cruel, you have got your work cut out haven’t you with your mums attitude, how on earth she thinks it makes children more aggressive later on is beyond me, I personally think she is controlling you telling you what you should and shouldn’t do, it’s outrageous! She’s being very selfish, so the rest of the family feel the same way, so sorry to hear this April0 she’s not thinking of what you would like to happen at all, in that case I would be putting YOUR baby into nursery, and this spending time with him 4 times a week would be stopped, if she cannot support your decision, she would be seeing him once, please let us know how you get on, really hoping things go well for you, sad to hear this
