Jumperoos?

As

I’ve seen a few people posting about the Sit me up seats whixh i had never heard about. Currently we put baby on a swing. He was 13 almost 14lbs at his 2 month appt 2 weeks ago. The weight capacity of the swing is 20lbs. We have a Jumperoo that we havent opened yet. Baby is just starting to hold his head up on his own and loves to kick when laying down and loves ti push himself up when i lay him on my chest for an inclined tummy time. Im thinking he would really enjoy the jumperoo soon as his neck gets stronger. Anyone else’a baby using and enjoying a jumperoo?

Also, how do you weight your babies in between the 2 month & 4 month appt to determine if baby is too heavy to use certain items safely?
