Cranky 5 month old

My five month old baby is cranky constantly I try putting him in the swing he cries any other activity he cries his little seat he cries. All he wants is to be held constantly and I love and adore him but sometimes it’s hard to get anything done especially since I also have a three year old . My boyfriend works a lot and helps when he can but I’m alone the majority of the time and it’s so stressful any tips or ideas my daughter was not like this when she was a baby.
