Husband constantly complains about the kids

Does anyone else's partners complain about the kids?

My partner always hates the fact that they need to be tended to because he misses out on having a shower straight away when he gets home, or he needs to help me when putting the kids to bed.

Its always my fault that the baby slept too much during the day and thats why she wont go down at the same time as her older sibling.

He complains the kids sleep in my bed and i should have taught them to sleep by themselves but i always did what was best for us and i wouldnt get any help if i did put them in their own beds. I feel comfortable knowing they are with me. Me and my partner haven't shared a bed in over a year.

He says hes an idiot for having kids and wishes that he didnt.

He had to mind them for one day and didnt have a clue what to do with them. I tried giving suggestions but he replied with "this is my issue that i have to deal with now". When i replied back saying "the kids are the issue?", he just responded yes. This was all said in front of them.

He can be so loving towards them and then change in an instant.

I dont know if this is normal behaviour.

Please dont suggest leaving as i wouldnt be able to since he doesnt know how to have them for a day let alone a weekend which is what he said he would want if we broke up
