Our nearly-2 year old has got very stuck on me and is refusing to engage much with dp, who does a lot of care of him incl 1-2 days a week, bathtime, etc. It's driving us both nuts and quite upsetting! He actually averts his eyes, yells for me, shrieks nonono if dp goes in at night, etc. Is this normal, why is he doing it, will it pass, please reassure /give any tips... thanks.... he is still breastfeeding which I suppose might be relevant, but not much.
